N2 - Clutter suppression is essential to radar signal processing,but it still suffers from some severe problems which need to be discussed in this paper. The moving target indication (MTI) is a commonly used approach in clutter cancellation, and is very effective when radar detecting moving targets in clutter interference environment. However, the wide notch developed by MTI filter result in significant signal losses for low-velocity targets, and thereby, brings serious negative impact in the detection of these targets. In order to solve this problem, a fast block normalized least mean square (FBNLMS) method for pulse radar is proposed in this paper, and it not only can suppress the interference but also protect the energy of low-velocity target. A multichannel fast block NLMS (MC-FBNLMS) algorithm is also developed to suppress the moving clutter which has non-zero Doppler frequency and spread Doppler spectrum. The effectiveness of the proposed approaches has been verified by experimental analysis.
