摘要

针对弹载步进频率宽带相控阵雷达的前视真实孔径成像以及地、海杂波背景中的目标探测应用,提出了基于方位向非均速扫描和最小二乘参数估计的距离-方位二维成像方法以及成像过程中的运动补偿方法。该方法运算量少且适合于扫描过程中的流水线并行处理,在高重频情况下的高速弹载应用中可以实现远小于波束宽度的方位分辨力。理论分析和仿真实验证实了方法的有效性。

Abstract

A novel method of two-dimensional real-aperture range-azimuth imaging and motion compensation was presented for missile-borne stepped-frequency wideband phased-array radar with application of target detection in ground or sea clutter background by using non-uniform scanning of beam in azimuth direction and least square criterion. Theoretical analysis and simulation result show that the method has advantages of low computation complexity, suitability of pipeline parallel processing during scanning and availability of azimuth resolution of far less than beam-width in high speed missile-borne application under the circumstance of high pulse repetition frequency( HPRF) .

Key words： missile-borne phased-array radar; high pulse-repetition frequency; forward looking imaging; motion compensation; real-aper-ture; wideband
