摘要

雷达信号处理中

由于目标信息未知

进行距离/速度/方位分选时会产生目标幅度损失.本文在分析信号处理中加窗影响的基础上

针对距离/速度分选采用汉宁窗、波束形成采用切比雪夫窗的系统

定量分析了距离/速度/方位分选所产生的系统损失

并提出插值处理、双门限检测两种方案以减小此损失.

Abstract

Loss in target amplitude results from range/velocity/azimuth transform in radar signal processing due to unknown information for the target.Based on the analysis of effects of window functions on signal processing

the system loss for range/velocity transform with Hanning window and azimuth transform with Chebyshev window is analyzed quantitatively.The of methods interpolation and detecting target with two thresholds are presented to cut down the loss.
