提出了一种新的用于步进频率ISAR成像运动补偿的方法.它利用常载频低分辨信号对运动目标进行跟踪,并利用回波解卷绕的相位获取目标较为精确的运动参数,利用高分辨步进频率回波信号精确地估计了目标运动参数,理论分析和仿真结果证明了所提出方法的有效性.
A new method for ISAR imaging motion compensation using step-by-step frequency is proposed.It uses the low-resolution signal of normal carrier frequency to track the moving target and uses the phase of echo unwinding to obtain the more precise moving parameters of the target. High-resolution step-frequency echo signals accurately estimate the target motion parameters. The theoretical analysis and simulation results show the effectiveness of the proposed method.
