MONOPULSE SECONDARY RADAR SYSTEM WITH MODE S Russian patent published in 2017 - IPC G01S13/44 

FIELD: radio.

SUBSTANCE: invention relates to radar systems for detection of targets, measurement of their coordinates, receiving additional information from aircraft equipped with beacons mode S of the fourth level, target tracking monopulse method. Said result is achieved by the fact that monopulse secondary radar system comprises an antenna system, a rotation drive connected through rotating transitions with transmitting and receiving antennae of the antenna system, hardware station containing at least requester, uninterrupted power supply, control terminal of radar, remote terminal, comprising communication equipment with the radar set for remote control of secondary radar based on the obtained signal via communication channels with radar information treated in interrogation unit, control transponder for adjustment and control of operation of the radar set by receiving interrogation signals and radiation response signals with radar information, the hardware station is additionally equipped with unit of tracking system, which provides synchronous and phase rotation of antenna systems of primary and secondary radars. System comprises a system of life support hardware station including, at least, temperature sensors, air conditioners and heaters. Interrogation unit includes at least, a synchroniser, a transmitter with modulator, power amplifiers, receivers, data processors. Control transponder includes at least horn antenna, receiver, transmitter, a data processor.

EFFECT: technical result-increase of accuracy of alignment marks from aircraft obtained from secondary and primary radar stations.
