Introduction
This post explains what I believe to be the most plausible explanation for the extraordinary features attributed to some UAPs by credible eyewitnesses. Here I provide you with the core facts that led me to my current assessment of plausibility.
The 2014 Nimitz case was selected for analysis because these events have been a key focus of the ongoing disclosure saga and they were well-documented by credible eyewitnesses.
I have not personally fully ruled out any of the many possible explanations for UAPs. If and when new information emerges, it will be factored into my assessment of probabilities and my conclusion may change.
Please note that all credit for the radar hypothesis goes to u/PinkOwls_.
Part 1: Hypothesis
Hypothesis:
The Nimitz UAPs were microwave radar-generated atmospheric electromagnetic phenomena similar to the Hessdalen lights.
What are UAPs?
Premise 1: The Condign Report
- The Condign Report is a top secret UK report commissioned to explain UAP phenomena to the highest levels of MoD leadership. It was considered so secret that the MPs responsible for MoD oversight weren’t told about it. It was completed in 2000, but its existence was denied until a FOIA request forced its release to the public in 2006.
- The MoD’s top secret Condign Report states that it is “indisputable” that UAPs exist and that UAPs exhibiting extraordinary features are “almost certainly” atmospheric electromagnetic phenomena.
What atmospheric electromagnetic phenomena could explain the extraordinary features of UAPs?
Premise 2: The Hessdalen Lights
- Decades of university-led scientific research on recurrent light phenomena above the Hessdalen valley in Norway demonstrates that luminous electromagnetic spheres with extraordinary features naturally form in Earth’s atmosphere.
- Published scientific descriptions of Hessdalen lights are consistent with the extraordinary features attributed to the Nimitz UAPs in credible
Unfortunately the hype got my attention so I have read the observation reports by the pilots.
Assumptions
I base my hypothesis on the following assumptions:
- the pilots observed a physical object and it's not misperception/illusion
- the object did reflect radar pulses and was tracked by shipborne and airborne radar
- there was a thermal gradient (or "membrane"/"bubble") which made the object visible in IR/TI
Here are more assumptions (related to the Nimitz-report and other "rumors" of Tic Tac-observations) I take into consideration:
- the Tic Tac was first observed above a "disturbance" in the ocean water; my assumption here is that there was water vapor/mist in the air above the disturbance
- it seems that during all Tic Tac-encounters at least one Radar was active
- it seems that Tic Tacs appear at the following locations:
- above bodies of water
- close to nuclear power plants: vapor/humidity from cooling towers; possible air defense installations
- military installations: air search radars, airborne radars
- the Tic Tac is of white color, possibly with a yellowish/reddish hue
- the Tic Tac has a soft border, something like a heat haze is observed, and there are possibly swirling patterns visible
Erratic movement because of Radar scan pattern
The fighter pilot reported that the Tic Tac was moving erratically, moving left, then instantly moving right, back, forth, a.s.o. It seemed as if the Tic Tac was able to instantly change its direction. If you understand how the scan patterns of a fighter radar (combined search and fire control radar) work, you will notice a similarity in the description of its movement and how the radar beam moves. Please watch the first 5 minutes of the following video: https://www.youtube.com/watch?v=Byqt8AJD4WE
I know it's a simulation game, and it's probably not the same Radar-type, but it's a good visualization of the principle.
Now it would be easy to recognize the relationship between radar and Tic Tac-movement if they were perfectly synchronized. You have to account for two fighters, both with active radar, possibly different scan patterns, and of course shipborne radar, probably a AN/SPY-1 (more to the SPY-1 later).
First hypothesis: The Tic Tac is guided/moved by the radar beams (main and side lobes).
This would also explain how the Tic Tac was mirroring the movements of the F-18 during the "turning fight". It was either the F-18's rada

So as part of a personal project I'm in the process of simulating and making a fall detector using a 2.7GHz microwave sensor with a range of 8m. I've been using MATLAB's example code to simulate each part of the radar as well as a target and a distance returned which can be found here: https://www.mathworks.com/help/phased/ug/designing-a-basic-monostatic-pulse-radar.html#d123e23746
As well as a radar based on the BISS0001 Chip with data sheet: https://cdn-learn.adafruit.com/assets/assets/000/010/133/original/BISS0001.pdf
This seems to work quite well but one thing I'm not entirely sure on is the design specifications and how I can translate them to my radar. In MATLAB's example they have a max unambiguous range of 5000m, a resolution range of 50m and a radar cross section of 1m^2.
Given I'm not expecting more than 1 target together I figure I don't really need to worry too much about maximum range and resolution range but regardless, since the range of my radar is 8m I've put the max range as 8m and as for the range resolution I've gone for 2m.
I'm not entirely sure that those are correct but given that I'll never have more than 1 target I think it might be OK but please let me know if not. The main thing is the Radar Cross Section as it's made up of a lot of properties I'm not definite on. Looking online at published data it seems 1m^2 is standard but does this not depend on the strength of my radar instead of just the target itself?

Been working on this project for quite a while now, and it finally is somewhat finished.
This is my version of a Tesla app combined with some real world object :-)
The display car can basically indicate a variety of data in more or less real time about my Model 3. Charging progress, battery level, when a software update is available (by flashing the car in blue, see video) or if frunk, trunk or doors are left open by indicating the corresponding part on the model car in red (see video that shows the frunk not being closed).
On the tech side, this is using a Raspberry Pi Zero driving a 32x64 LED matrix. The car data is coming in via Teslamate's MQTT integration (which I am running on a separate Pi to collect all my drive details). The LED matrix is controlled via HZeller's RGB matrix controller (Python binding).
The display also uses a microwave radar sensor to detect motion, so it does not run all day long without anyone being around.
The base is 3D printed, the car and the dome are laser cut acrylic sheets, all based on designs I made.

This Microwave Radar Sensor Module, like most other ~£10 ones, are built on a BISS0001 PIR Sensor chip. However, looking around you see a lot of comparisons between PIR and Microwave sensors with many articles titled something like 'Should you use microwave radars or PIR with your Arduino project'.
How does a Microwave sensor use the PIR differently?

Hey everyone, this is my first post in this sub.
I'm just here to share one of my recent designs, and my first true RF design that I made in EAGLE 9.6.It is a 6 layer hybrid stack with L2 and L5 being solid planes.
To be honest, I did reference some of TI's design for the antennas and power regulator specifically. Also, I still have to do some error checking and go over my usual final review for this PCB before I get it made. For the images attached, layer 3 and 4 are separated by a 28mil dielectric, which is the reason many of the signals on those layers overlap (I do not think EMI will be an issue).
I do have one question though: how much do you guys think this will cost per bare board without assembly? My estimate is $250 per board in an order of 5 which is acceptable.
If anyone finds any issues in my current design feel free to let me know!
Some issues I need to fix:
- Add more VSS stitching vias
- Give passive components (specifically decaps) more room
Specs:
- Laminate: FR4 + Rogers 4835 LoPro (only top layer)
- Layer count: 6
- Impedance control: 1 layer
- Total thickness: 1.29mm
- Length: 90.81mm
- Width: 58.42mm

It's really important to me i need it to pass my exams and it's not available anywhere in my country
