Method and device for detection of pulses received by a secondary radar by analysis of phase.

摘要

The invention relates to a process and a device for detection of the mixtures of pulses received by a secondary radar by analysis of phase. & br / the reception antenna of a monopulse secondary radars delivering a sum signal (sigma) supplied by the sum pathway and a difference signal (delta) supplied by the difference channel, the process according to the invention consists in analyzing the phase difference between the sum signal (sigma) and the difference signal (delta), the mixture of at least two pulses received is detected by a phase difference, the value of which is substantially different from 0degré or 180degré. & br / application: detection of pulses mixed received when the operating frequencies of the transponders are very close.
