The invention concerns receiving systems. It relates to a receiving system comprising an analogue-to-digital converter (4), a recursive filter (6), a buffer memory (8), a pattern recognition stage (10), a processor (12) and a detector circuit (14). According to the invention, after filtering to remove jamming signals, the presence of an interference pulse is determined by comparison of amplitudes, and the pulses held in the buffer memory are sent back to the input. Application to the processing of radar and sonar signals. <IMAGE>
