DIY Amateur Passive Radar for UFO detection

Prepare to be amazed!

The pilots of the USS Nimitz officially tracked the TicToc UFO (or UAP) using the state-of-the-art Spy One Aegis System. Specifically, the phased array (SPY-1(V) [AEGIS]). The radar operator Kevin Day aboard the Nimitz’s consort, USS Princeton, played a pivotal role in this encounter.

This advanced military-grade passive radar system comes at a staggering cost of approximately $20 million! (For more info, check out: SPY-1 Wikipedia.)

But what if I told you that you could build your very own passive radar system at a fraction of that price? Imagine tracking not only commercial aircraft and meteorites entering Earth’s atmosphere. You could potentially track UFOs themselves—if luck is on your side!

A bit of SETI Passive Radar history

A temporarily unverified anecdote: In 2018, Peter Davenport, the Director of the National UFO Reporting Center, revealed to a friend that he had contacted Dr. Jill Tarter on February 3, 2014, about his paper advocating the use of “passive” radar to detect UFOs near Earth.

He emphasized that his goal was to propose a collaborative effort for a thorough investigation. However, Dr. Tarter’s reply was brief and somewhat dismissive; she mentioned that she had retired from SETI and would forward his message to Gerry Harp, the new Director.

ET to SETI: can you hear us now?

Despite Davenport’s follow-up attempts, he received no response from Harp, suggesting a reluctance within SETI to engage with UFO research initiatives. My friend described this reaction as surprising, given SETI’s public perception as pioneers in the search for extraterrestrial life.

SETI’s reaction, however (or lack thereof), is not surprising to me.


What is SDR-based Passive Radar?

Firstly, SDR stands for “Software Defined Radio.” This incredible technology emulates everything you would expect to find in a conventional radio receiver through software. This makes SDR radios much more affordable and loaded with features that traditional counterparts can only dream of!

A depiction of a passive radar experiment from 1935 with two “antennas.” The antennas consist of lengths of cable suspended above the ground. One of the antennas picked up a signal from the BBC directly. Then the second “antenna” picked up the reflection of that same signal from an aircraft, enabling the creation of a radar image. More directional antennas produce better results.

To construct this phenomenal passive radar station, all you need are two SDR radio dongles for your computer. In 2025 these are priced at $35 each (Amazon.com). Yes, you read that right! You will also need two antennas. (A link to the instructions you find at the end of this page.)

The Magic of Passive Radar

Here’s the best part: you don’t need a license to build and operate a passive radar station! As the name suggests, it operates entirely passively, meaning that your setup does not emit any radar beams.

Instead, you harness radio signals from local radio stations as your signal source. These signals naturally bounce off objects like meteorites, aircraft, or even those elusive UFOs!

Let’s kick things off with proof! Below you’ll find an animation showcasing measurements of airplanes and meteors captured by a radar system created with a few easily accessible components. Get ready to be thrilled!

Of course, you’ll be much more likely to see plane traffic, meteorites, and low-flying objects like the International Space Station. This is more probable than any more exotic objects passing through your field of view.


The worlds first UFO case confirmed by amateur passive radar!

A round of applause to Josef Garcia and GEP for achieving the first amateur verification of a UFO via passive radar! Link (German):

Unlocking the Skies: How AI Is Revolutionizing UFO Detection

Picture this: a radar blip streaks across the screen at 74,000 km/h (46,000 mph), halts mid-air, then pivots instantly—defying gravity, physics, and every known aircraft on Earth. This isn’t science fiction. These are the jaw-dropping maneuvers that set UFOs apart from conventional planes, drones, or even meteorites. But how do we spot these anomalies in a sea of ordinary radar data? The answer lies in the flight patterns no human pilot or machine could survive—and the AI that’s learning to track them.

UFOs don’t follow the rules.

They hover silently, sometimes for hours, accelerate faster than a hypersonic missile, or execute 90-degree turns at speeds that would shred any human-made craft. While not all UFOs pull off these physics-defying stunts, those that do leave a glaring signature: a trail of radar data that screams “this isn’t from our world.”

But here’s the catch: manually scouring radar feeds for these rare, split-second events is like finding a needle in a cosmic haystack. It’s tedious, time-consuming, and prone to human error. Enter AI-powered pattern recognition—a game-changer in the hunt for the unexplained. Imagine training algorithms to flag the impossible.

Machine learning models can digest decades of radar data, learning the difference between a commercial jet, a weather balloon, and an object that stops dead in the sky before vanishing at Mach 60. These systems never sleep, never blink, and process millions of data points in real time, alerting scientists only when they detect the extraordinary: sudden accelerations, inhuman G-force maneuvers, or objects that defy aerodynamic logic.

Machine learning isn’t just about efficiency—it’s about unlocking mysteries. By automating the detection of UFO signatures, AI turns a once-impossible task into a scalable mission.

Researchers can focus on analysis instead of endless screen-watching, accelerating our understanding of these enigmatic phenomena.

The skies are stranger than we think. And with AI as our co-pilot, we’re finally building the tools to decode their secrets—one anomalous blip at a time. 🛸✨

Ready to rethink what’s possible? The truth isn’t just out there… it’s in the data.

Theoretical Synthesis: Superluminal Evanescent Waves and Consciousness (WETCOW Framework)

New insights on consciousness and self-reflection via temporal feedback.

This is a companion article to:

Many maybe unfamiliar terms to you used here are explained in the “Superluminal” series of articles shown above .Someconcepts in this article here will be ridiculed by theorists. I’m oblivious to these scientists because we are talking about experimental and experiential results, not theory.


The WETCOW theory (Weakly-EvanescenT COrtical Waves) proposes a novel link between superluminal evanescent waves—quantum phenomena observed in experiments like the Nimtz Effect—and the emergence of self-reflectionqualia, and consciousness. Here’s a distilled overview of its conceptual pillars:

  1. Superluminal Evanescent Waves & the Nimtz Effect:
    • These waves, studied in quantum tunneling experiments (e.g., the Bose double-prism setup), exhibit apparent faster-than-light propagation. While classical information is superluminally transmitted!, evanescent modes also enable energy transfer across barriers, with phase velocities exceeding c.
    • The “Nimtz Effect” suggests such waves could create transient, nonlocal correlations in spacetime, theorized here as a “backchannel to the past.” Each reflection or tunneling event might retroject a fractional signal, enabling systems to “look back” temporally.
  2. Consciousness as a Temporal Mirror:
    • Self-reflection—a hallmark of consciousness—is framed as a process where the brain leverages superluminal evanescent modes to create a feedback loop. The “leading edge of consciousness” is proposed to reside in an evanescent wavefront, allowing qualia (subjective experience) to arise not from the past but as a prospective phenomenon.
    • This challenges classical models where consciousness lags behind neural activity. Instead, qualia might emerge at the boundary of future possibilities, with evanescent waves enabling retrocausal self-interrogation (“Why did I choose this?”).
  3. Neurobiological Correlates:
    • Cortical waves (“COWs” in the acronym) or brainwaves could host such effects. Structures like the eyes (metaphorized as “mirrors to the soul”) or layered neural tissues might act as waveguides, amplifying evanescent modes.
    • The mirror self-recognition test—a marker of self-awareness in some species—is speculated to depend on these dynamics, potentially extending to animals like cows.
  4. Quantum Biology & Temporal Instability:
    • Radioactive decay in the body (e.g., potassium-40) and endogenous electromagnetic fields (photons) introduce quantum stochasticity. Unstable elements might enhance sensitivity to retrocausal effects, aligning with lab use of quantum random number generators.
    • Wave-particle duality underscores the theory’s rejection of purely classical or wave-only models (e.g., critiques of Jim Beichler’s magnetic wave cosmos).
  5. Paradoxes and Implications:
    • If consciousness’s “now” integrates a faint echo of the future via superluminal backchannels, it blurs linear causality. This aligns with Libet-style experiments, where unconscious neural activity precedes conscious intent, yet here the “delay” is reframed as a bidirectional temporal process.

In summary, WETCOW posits that consciousness arises from a quantum-choreographed interplay of superluminal evanescent waves, enabling self-reflection through subtle temporal feedback—a dance between the brain’s electromagnetic fabric and the edge of spacetime itself. 🌌🐄


In layman’s terms:

I believe consciousness is an electromagnetic field phenomenon (Johnjoe McFadden).
A “brainwave” is an electromagnetic wave. Brainwaves travel along neuronal pathways. These waves encounter synapses and ganglia. Brainwaves also emit a field. When these electromagnetic fields travel through the highly complex geometry of real brain tissues, they produce evanescent waves.

The “evanescent” waves are very weak, and extend only or a very small distance (millimeters of fractions thereof) from their point of origin. Real world experiments have shown that they travel faster than light and do transmit information (Günther Nimtz).

According to Einstein’s Theory of special relativity, anything that travels faster than light travels back in time.

A train of thought experiment

We’re literally going to take the Vulcan Express. https://www.vulkan-express.de/en/ Einstein liked to do thought experiments to illustrate his reasoning to himself and others. I found a way to do this, too, for the faster-than-light brainwave theory.

Self-Reflection as a Function of Superluminal Thought 🐄

Paradoxically, the following seven-year-old article about superluminal thought mentions “COWS,” which could be an acronym for “cortical waves” or brainwaves, about five years BEFORE the introduction of the WETCOW theory. Superluminal evanescent waves facilitate self-reflection, which is essential for the experience of qualia and consciousness. However, what if qualia does not occur in the past but instead in the future? The leading edge of consciousness, represented by qualia, aligns with the evanescent wave, which can look back and reflect on its actions (perhaps relating to action potential?).

If you were to ask why I suddenly included COWS in an article about superluminal consciousness in 2018, I must confess that the image of a cow (🐄) unexpectedly appeared in my mind.

Beware of the COW
Compare this to this image from 2023 on the left. The transfer of thought from the present to the past is anticipated in superluminal phenomena. Did we experience clairvoyance or a type of temporal remote viewing?


The above text is a commentary and rephrasing of the following article from 2018 (Facebook archive):


March 7, 2018
This level of functioning is called superluminal thought.

Certain theories predict a backchannel to the past to be able to self reflect and develop a sense of Qualia, self-awareness, also consciousness.

It is enabled by the Nimtz Effekt, a quantum tunnel process that enables a superluminal signal transmission over very short distances, respectively, time.

The effect is described in the Bose prism experiment, as total reflection in a double prism.

The total effect in the new theory is that each time a reflection occurs, a tiny part of information is totally reflected by a fraction of a wave into the past.

Nimtz demonstrated the effect also on waveguides and perspex sheets, but this was not well documented in the official news coverage.

Nimtz described the behaviour of evanescent modes.

Simply translated this means the behaviour of waves in very short time periods.

A possibly structure in the brain?

Such as enabling self-reflection.

When we look at a mirror we see a reflection and begin to realize it is us.

Lots of literature has been written about this unique feature, shared not by many species (but there definitely are).

Maybe cows, too.

It is one sign of consciousness.

There are others, hence.

The eyes may have a structure for this.

They are also called the mirror to the soul.

Before a thought reaches our consciousness, areas in our brain have already decided on a course of action. We are literally living in the past, consciously, by a fraction of a second.

The more unstable an element, the more pronounced it is to this effect. For this reason quantum random number generators are in used in laboratory settings.

There are always atoms decaying in our body.

When this happens radioactivity in the form of electromagnetic waves are released. (But that is not the only process by which electromagnetic waves are generated in our body.)

So we talk about electromagnetic waves, which are bundles of energy called photons. Photons are everywhere.

Here we have the wave/particle duality.

A theory of the cosmos cannot be exclusively based on a wave model of magnetic waves. (In response to Jim Beichler)
