摘　　要：在动态规划阵列的基础上，为了降低峰值旁瓣电平，首先提出了分区动态规划阵列，并与其它几种优化布阵方法进行了比较，结果表明：分区动态规划阵列具有相当的优越性。同时，该优化布阵方法应用于微波成像大阵列系统中，获得了较好的峰值旁瓣电平，再一次证实了分区动态规划法的优化性能。The application of dynamic programming method to themmingmethod to the design of optimumthinned arrays is described firstly, then a mew method of dynamic programming with partioned pre-processing for lowing peaksidelobe level( PSL)is presented. Two examples are given using DPP to demonstrate its performance.Several'optiml'arrays are compared,showing that DPP has superior that DPP has superior advantages.Finally,DPPis appliedto the Microwave Imaging Radar Test System with Large Array and get satisfied PSL.
