An experimental bistatic radar system is described which detects and tracks torch targets more than 150 km from the receiver using echoes from a non-cooperative FM radio transmitter. The system concept and performance limitations are described, followed by details of the processing used to implement the system. We describe an adaptive filter algorithm that is used to effectively eliminate interference and strong signals from receptor channels. A computationally efficient algorithm for the detection of targets using Doppler-sensitive cross-correlation techniques is described. A simple false alarm rate constant algorithm for target detection is described, along with a description of a Kalman filter-based target association algorithm. Representative system results are provided and compared with truth data derived from compressed air control data.
