RADAR TRANSCEIVING MODULE Russian patent published in 2001 - IPC

FIELD: radiolocation. SUBSTANCE: invention can be employed in pulse radar systems of millimeter and centimeter ranges used to detect shoreside and surface targets, to measure their coordinates and motion parameters. Proposed radar transceiving module incorporates antenna unit with rotation drive connected via rotary adapter and SHF path to transmitter that includes magnetron generating SHF radio pulse signals and receiver that includes circuit converting radio signal reflected from target to video signal fed over communication channel to external radar indicator as well as communication and synchronization unit coupled to receiver and transmitter and meant to generate signals controlling receiver and transmitter. Specified transmitter has unit forming synchronization pulse signals supplied to external radar indicator and coupled to magnetron. In agreement with invention unit forming synchronization pulse signals is placed in power supply circuit of magnetron and incorporates circuit generating synchronization pulse signals from anode current or voltage of magnetron. So time of generation of specified pulse signals is referenced to time of generation of probing SHF radio pulse signals by magnetron. It is advantageous to transmit video signal and synchronization pulse signal to external radar indicator over one cable. In this case specified signals transmitted over cable will have opposite polarity. It is expedient that radar transceiving module has radiator and reflector of test SHF radio pulse signal of same frequency as probing SHF radio pulse signal but delayed by fixed time with reference to the latter. EFFECT: design of radar transceiving module displaying high operational characteristics. 4 cl, 1 dwg
