对于目标分辨,常规的方法是采用FFT算法估计多普勒频率和幅度,该方法通用性好,但是当目标信号之间幅度差异较大时,对多目标不能有效分辨。本文介绍一种基于RELAX算法的多目标分辨方法,可消除多目标之间的相互影响,实现目标之间的完全分离,达到多目标分辨的目的。仿真结果表明,RELAX算法较FFT算法效果更好。 For target discrimination, the conventional method is to use FFT algorithm to estimate the Doppler frequency and amplitude. The method has good generality, but it can not effectively distinguish the multi-target when the amplitude difference between the target signals is large. This paper introduces a multi-target resolution method based on RELAX algorithm, which can eliminate the mutual influence between multiple targets and achieve the complete separation between targets and achieve the goal of multi-target resolution. Simulation results show that RELAX algorithm is better than FFT algorithm.
