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.
however, the signals should be observed simultaneously in both domains.
distribution concept offers a new approach in radar signals
The paper presents some results of compressive
concept and Hough transform application to intra-pulse modulation analysis of
Linear frequency modulation within the pulse was considered.
