ELINT/ESM类型的电子情报在初级层使用拦截雷达信号的参数测量。现代雷达使用的波形越来越复杂。有些波形被有意地设计成几乎不可能被截取。现代雷达信号的主要特征隐藏在它的时频结构中。由于雷达波形相对简单，过去对雷达信号特征提取问题分别在时域和频域进行考虑。然而，今天，应该同时观察到这两个领域的信号。时频分布概念为雷达信号分类识别提供了新的思路。本文介绍了霍夫变换在雷达脉冲内调制分析中的一些应用结果。考虑了脉冲内的线性调频。
ELINT/ESM type of electronic intelligence in the primary layer uses parameters measurements of intercepted radar signals. Nowadays modern radar uses more and more complex waveforms. Some waveforms are developed intentionally to make their intercept almost impossible. The main distinctive features of modern radar signal are hidden in its time-frequency structure. In the near past the problem of radar signal feature extraction was considered in time or frequency domain separately, because radar waveforms were relatively simple. Today, however, the signals should be observed simultaneously in both domains. Time-frequency distribution concept offers a new approach in radar signals classification/identification. The paper presents some results of Hough transform application to intra-pulse modulation analysis of radar signals. Linear frequency modulation within the pulse was considered.
