Process for the phase detection of a received radar signal

The present invention detection relates to a process consisting in sampling the intermediate frequency signal at a sampling frequency fe such that fe is equal to alpha B, alpha being a number greater than or equal to 2 and B being the width of the pass-band, the intermediate frequency fi and the sampling frequency being in a ratio such that fi = (k +/- 1/4 )fe, k being an integer. The invention is applied. <IMAGE>
