摘　　要：动目标改善因子是衡量动目标性能的重要指标。分析了影响动目标改善因子的几种因素,结合实际项目工程应用分析了平台运动杂波谱对动目标改善因子的影响,最后提出了一种基于CORDIC算法的有效改进平台运动杂波谱抑制的措施。仿真数据实验结果证明了该方法的正确性和有效性。The improvement factor of the moving targets is an important indicator for measuring the performance of the moving targets. Several factors affecting the improvement factor of the moving targets are analyzed. Combined with the actual project engineering applications, the influence of the clutter spectrum of the platform motion on the improvement factor of the moving targets is analyzed. Finally, a method of effectively improving the clutter spectrum suppression of the platform motion is proposed based on the CORDIC algorithm. The simulation results prove the correctness and effectiveness of the method.
