30hours/blah2 — reverse-engineered prompt

Build me a real time passive radar project that works with common SDR hardware and shows the processed radar output in a browser. I want two channel capture, one reference signal and one surveillance signal, with the backend processing the IQ data into delay Doppler maps. The maps should be sent through a simple API and displayed on a web front end so I can watch the radar output live.

Please include a config file where I can change the processing settings and choose the SDR setup. It should support SDRplay RSPduo, USRP B210, two synced HackRFs, two synced RTL SDRs, and KrakenSDR with two channels. Add a way to press the spacebar in the web page to record raw IQ data, and also save the delay Doppler maps as JSON arrays.

Make it easy to run with docker compose, with separate services for the radar processor, API middleware, and web UI. Look up current docs online if you need to.
