Abstract

Abstract:

In this paper, a new approach to spatial angle frequency shifting spectrum compensation for forward looking radar is proposed. The algorithm compensates the clutter Doppler frequency for the range cell before using spatial angle frequency shifting, which overcomes the problem of decreasing moving target detection performance, caused by the spatial angle frequency shifting algorithm to enhance the sidelobe of the reference range clutter spectrum. Experimental results show that the improved algorithm can obtain obviously better performance than spatial angle frequency shifting, without performance loss under radar clutter with some uncertain errors.

Key words: forward looking radar, clutter spectrum, spatial angle frequency shifting, Doppler compensation
