The lecture describes how to build your own passive radar system using relatively low-cost hardware and free software. The lecture describes how to build your own passive radar system using relatively low-cost hardware and free software. Passive radar systems allow you to determine the position and velocity of aircraft, etc, using broadcast TV and FM radio transmitters as illuminators. The system works by watching the direct path and reflections from L transmitters using M coherent receivers at N locations. From the raw data we extract estimates of bistatic range, doppler and angle of arrival. These estimates are fed into a tracking algorithm that attempts to sort airplanes from clutter and noise.
