A New Super Resolution Algorithm in Ship-Borne Radar

Abstract

In ship-borne radar, because of the influence of interference factors such as the correlation of background array noise and the coherence of targets and so on, the performance of high-resolution algorithms such as MUSIC is degraded. In this document by pre-whitening of background array color noise, de-correlation of coherent targets, compensation of amplitude phase mismatch, pre-whitened-Constrained-MUSIC algorithm is put forward, which can effectively resolute ship target and first-order sea echo in ship-borne radar. Furthermore, the algorithm performance is compared with other algorithms, result shows that pre-whitened-Constrained-MUSIC can be applied effectively in high-resolution processing in ship-borne radar.
