回波信号的理解与幅、相调制特征的分析

Analysis of Return and Its AM & PM Features

在分析了监视雷达飞机回波调制现象、系统归纳了监视雷达飞机回波性质和特点的基础上,提出了从实际监视雷达回波中提取相对不变的幅度、相位调制特征的相对量分析法,并讨论幅度、相位调制特征的物理意义与飞机分类的效能,这对监视雷达飞机回波分析、识别特征提取、目标自动分类系统设计都具重要实用价值.

This paper makes an approach to the modulation features of returning echo, and sums up systematically its characteristics for the surveillance radar. And the analysis of relatively charging values, used for extracting the AM & PM characteristics that is relatively invariant in the real surveillance radar, is proposed. The physics and classified effectiveness of the AM & PM characteristics is also given in this article, which is available for the return analysis, extraction of recognition features and design of automatic target classification.
