The Fusion Algorithm for FBLMS and Batches Correlation

Interference cancellation based on the frequency-domain block least-mean-square (FBLMS) algorithm and the cross-correlation based on the Batches algorithm are two important steps operating successively in passive bistatic radar (PBR) system. In this paper, a fusion algorithm is proposed, which has a dual function of cancellation and cross-correlation. Parameter design and computational complexity of the proposed algorithm have been discussed in detail. The results indicate that the proposed algorithm has lower computational complexity while preserving the cancellation performance and integration gain. The real data verification have proved the effectiveness of the proposed algorithm.
