摘要

本文寻求一种在扫描实孔径雷达中

利用方位信号处理获得优于天线波束宽度的角分辨力的途径。文中建立了扫描过程的数学模型

并提出了采用广义逆滤波处理实现波束“伪压缩”的方法

阐明了这种方法的物理本质

解决了这种方法最佳解的确定问题。文中用这种方法对雷达实测数据进行了处理

使雷达的角分辨力提高约4倍。

Abstract

This paper concentrates on the problem of finding a way to obtain angular resolutions better than the beam width of real aperture radars by means of azimuth signal processing.The model of the scaning process of real aperture radars is established

and the antenna pseudo-compression method is proposed based on generalized inverse filtering.The criterion of determining the optimum solution of the method is also presented.And the angular resolution is improved by a factor of about 5 by using this method in experiments.
