FIELD: radar ranging.SUBSTANCE: invention relates to radar ranging, particularly, to coherent-pulse radar near field devices using pulse emitted radio signal with phase shift in range of (0 - π/2) from period to period and double frequency conversion of received radio signal. Technical result is achieved due to introduction to transceiver system of automatic frequency tuning of second self-contained generator.EFFECT: technical result is provision of discrete and smooth adjustment of frequency in interference conditions ensuring stability of second intermediate frequency.1 cl, 4 dwg |
