RADAR WITH INVERSE SYNTHESIZING OF APERTURE AND MULTIFREQUENCY PROBING SIGNAL Russian patent published in 2000 - IPC

FIELD: radiolocation. SUBSTANCE: proposed radar is designed for hardware realization of known method of generation of two-dimensional radar images of tracked air targets with rectilinear flight trajectory. With this in mind mix of traditional radar including master generator, key, mixer, coherent transmitter, antenna switch, antenna, analog-to-digital converter, antenna control system, unit displaying two-dimensional radar images is supplemented with two potentiometric pickups, three phase detectors, monopulse radiator, unit of elements of line part of receiver of summary channel, unit of elements of line part of receiver of difference channel of elevation angle, unit of elements of line part of receiver of difference azimuthal channel, frequency synthesizer on surface-acoustic waves, amplitude detector, range measuring system, two keys, control circuit, four analog-to-digital converters, unit computing parameters of flight of target, unit of radar recognition, digital device of generation of controlled delay, unit of compensation of translation, unit of two-dimensional fast Fourier transform, operator's control panel. EFFECT: authentic identification of classes of air targets. 1 dwg
