摘要
步进频率信号脉冲综合后存在两种成像冗余,本文分析了他们对一维距离像的影响,提出了一种距离像拼接算法:局部同距离取大法,该方法在目标进行像拼接时利用了高分辨距离像冗余信息,因此对静止目标以及运动目标均有效。对仿真数据和外场实测数据的处理均验证了该方法的有效性。
There are two kinds of profile redundancy after the stepped frequency signal pulse is synthesized.Its effect on 1 dimensional range profile is analyzed;a range profile splicing method,named iso-range local-maximum-picking method is proposed.The method is to use high resolution range profile redundancy information while splicing target profiles.So,it is valid for both stationary and moving targets.The processing for the simulated data and field measured data verifies its effectiveness.
