方位预求和在多普勒波束锐化信号处理中的应用

The Application of Azimuth Pre-summation In DBS Singal Processing

本文提出了将方位预求和应用于多普勒波束锐化信号处理的思想。在多普勒滤波前进行方位预求和可以最大限度地降低天线旁瓣泄漏信号对成图质量的影响,并可避免某些方位分辨单元的不完整多普勒历程对成图的影响。文中给出了实现方法,并进行了计算机仿真。

This paper advance the method of applying azimuth pre-summation in DBS singal processing.Applying azimuth pre-summation before doppler filter can deeply reduce the influence to picture quality because of the leak singal of antenna lobe,and also can avoid the influence of incomplete doppler course of some azimuth unit. The realization method and computer simulation are provided.
