Implementation of sequential algorithm in batch processing for clutter and direct signal cancellation in passive bistatic radars

Passive bistatic radars are an important batch of scout radars that use the signals of other independent transmitters as illuminators of opportunity. Cancellation of clutter and multipath is an important problem in these radars. This problem is exacerbated as the transmitter signal is not under the control of designer. In this paper, we propose a novel algorithm for clutter and multipath cancellation in the passive radars that called sequential cancellation algorithm-batch (SCA-B). Indeed, the SCA-B is a generalization of some recent algorithms such as the ECA, the SCA and the ECA-B that act based on projecting the received signals in a subspace orthogonal to both clutter and pre-detected targets. In this paper, the SCA-B algorithm use for static and non-static clutters cancellation. The SCA-B provides an admissible performance with low complexity.
