DEVICE FOR RECEIVING AND PROCESSING RADAR SIGNALS FOR COUNTERMEASURE ANALYZER.

摘要

P This device comprises, for reception, a spectrum analyzer of the input signal itself comprising two multipliers (2, 3) for performing in parallel two multiplications of the input signal respectively by two frequency ramps. linearly modulated in frequency, of band 2B (B being the frequency band of the input signal) and of duration 2T, offset with respect to each other by a duration T, an adder (11) for adding the output signals of these two multipliers, and a dispersive filter (12) of band B and delay T, disposed at the output of the adder. BR/ This device also comprises, for processing, means for recognizing the carrier frequency of the radar emissions thus intercepted, taking into account the particular nature of the output signals of the spectrum analyzer. BR/ Application: countermeasures. / P
