That YC "let's put AESAs on interceptor drones" pitch is kinda interesting. I hate YC as much as the next guy, but reducing the role of human skill and focusing on enabling higher aspect intercepts is a great idea. I'm less sure that "lighting up the target with FMCW the whole time" is the right way

There is no "camera vs lidar" debate outside of Musk fan echo chambers, it's camera vs lidar and radar and camera. Sensor diversity is important because each modality has advantages and disadvantages, so you want 360 coverage of all three.
Also, FMCW lidar is great at long range depth/motion.

I haven't send the boards to fabricate yet, so if anyone wants to review and give feedback, that would be awesome. It's been a long time since I last designed hardware.

AN/APA-127 provided frequency-modulated continuous-wave RF energy. A triangular FMCW signal is shown below. The transmitted signal is in red, and the received signal is in green.

A week ago I posted here a PCB design I've been working on with an ADF4158 and HMC391 for the LO of an FMCW 10 GHz radar. Thanks to all who reviewed this and sent suggestions. I have now switched to a 4-layer FR4 stackup, added M2 mounting holes and done other tweaks.

Spotted on the 20m band (14205 USB) - Regular (10 min) beacons that look a lot like LoRa (well, chirped modulation of some kind), but are contained within a 3 kHz channel. The beacons seem to alternate between data packets and just FMCW. Seen anything like this @destevez.net ?

I've been designing a PCB with an ADF4158 and HMC391 that generates a 3.9 - 4.45 GHz LO for an FMCW radar. The idea is to use this with a subharmonic mixer to build a radar in the 10 GHz amateur band, inspired by the ADALM-PHASER but much cheaper.
