MONOPULSE RADAR STATION Russian patent published in 2005 - IPC

FIELD: the invention refers to radiolocation systems primarily to coherent target detecting radars with continuous radiation.

SUBSTANCE: exceeding requirements are demanded from these systems using a linear frequency modulation signal additionally modulated on the frequency to reduce the time of observation of the scene and an amplitude summary-differential mono pulse pattern of direction finding of targets working on mobile bearers. The arrangement has an antenna block, a summary-differential transformer, an antenna switch, a power amplifier, a directed coupler, a commutated filter of transmission, a multiplier of a frequency, a synthesizer of a probing signal, a driver, a generator of manipulated sequences, a synchronizer, an arrangement for processing of information, a measuring unit of the speed and the angle of drift, commutated filters of summary and differential channels, a two-channel summary-differential receiver, phase detectors of the summary and the differential channels, amplifiers of a Doppler frequency of the summary and the differential channels, an automatic regulation of strengthening, blocks of Doppler filters of the summary and the differential channels, interrogation blocks of the summary and the differential channels, a combining block of quadratures, an angle discriminator, a divisor, an antenna driving gear, two-channel amplifier of a high frequency, a two-channel balance mixer, a two-channel amplifier of an intermediate frequency, blocks of secondary and initial processing.

EFFECT: provides possibility for working of an airborne mono impulse radar with a single receiving-transmitting antenna in continuous mode.
