Abstract
Pulse compressed signal enhances the jamming immunity of a radar operating with such a signal. The matched filter is one of the most important elements in the pulse compression technique. A model of a matched filter for a chirp signal was synthesized using the Simulink tool of the Matlab software. Interference signals were feed to the input of the matched filter and output signals were measured. The matched filters degree of suppression of these interference signals was assessed. Conclusions were made about the jamming immunity of radar operating with chirp signal.

Pulse compressed signal enhances the jamming immunity of a radar operating with such a signal
The research was made at different ratios of the characteristics of the filter and chirp signal
The simulation uses a matched filter for a chirp signal as a part of the radar’s receiver
Summary
Pulse compressed signal enhances the jamming immunity of a radar operating with such a signal. The simulation uses a matched filter for a chirp signal (filter matched to linear frequency modulated signal of the radar) as a part of the radar’s receiver. The receiver is a functional element of typical radar that uses compressed signal (linear frequency modulated signal).
