Analysis and research of an adaptive side-lobe cancellation performance improvement method

In this paper, we first introduce the conventional adaptive side-lobe cancellation algorithm,for the factors affecting the performance of side-lobe cancellation, the method of adding delay nodes to the auxiliary is proposed. Then, we simplify the algorithm on this basis, and finally, the effects of improvement are compared and verified. The results show that simplified method has high practical value in improving the side-lobe cancellation performance without increasing the amount of calculation.
