This repository contains processing code for a software defined radio based passive radar. Passive radars don't transmit any signals of their own - instead, they locate targets by detecting the echoes of ambient radio signals that bounce off of them. Uses FM radio broadcasts as the illuminating signal. This is not realtime - it analyzes stored PR information and displays it, and it's not quick. It does tell you how to collect your own radar data, however, as well as which SDRs are feasible.

Software and documentation for getting media signals (FM RF) out of VHS VCRs, processing them, and writing them out to lossless digital formats for archival.
