Abstract

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. Timefrequency distribution concept offers a new approach in radar signals classification/identification. The paper presents some results of compressive concept and Hough transform application to intra-pulse modulation analysis of radar signals. Linear frequency modulation within the pulse was considered. Keywords: signal spectrum, chirp transform, compressive receiver, Hough transform, intra-pulse modulation.
