Abstract
The multipath clutter cancellation, the most computationally demanding part of signal processing in passive bistatic radar (PBR), is a key challenge in real-time processing. However, the previous extensive cancellation algorithm (ECA) versions have their limitations in parallel implementation. In this study, an advanced version of ECA is proposed for multipath clutter cancellation in passive radar. The proposed method can improve the computational efficiency via dividing the whole signal into more batches than ECA-batches and yielding an excellent cancellation performance at the same time. Simulation and experimental results following the theoretical analysis verify the performance of the new approach, which provides a valuable basis for real-time signal processing in PBR.
