Abstract: A passive radar imaging algorithm is presented in the paper. Receiving the reflected signals from multiple television stations located at various aspect angles, the algorithm can image moving object by synthesizing multiple sub-apertures of the television stations which are induced by the small angular rotations of the object into a wide-angle equivalent aperture. In addition to the low complexity in computation, the algorithm only uses the carrier waves of television stations while requires a small rotation angle of object in the area where dense television stations are available. Finally, the theoretical validity is illustrated by simulation results.
