Passive Radar Imaging Algorithm Based on Subapertures Synthesis of Multiple Television Stations

In this paper, we presents a passive radar imaging algorithm based on signals received from multiple television stations at various aspect angles and bistatic equivalence theorem. The algorithm reconstructs a target image by synthesizing the subapertures of multiple television stations available into a large equivalent aperture. In addition to the high efficiency in imaging and low complexity in computation, the algorithm requires neither transmitting wideband signals nor large angular rotations of object. Its validity is shown from simulation results
