FIELD: identification of air targets by formed two-dimensional radar images. SUBSTANCE: invention is related to capability of radar to identify air targets on basis of narrow-band coherent sounding by formed two-dimensional radar images. It is intended for aperture realization of method of generation of two-dimensional radar images of tracked air targets with rectilinear flight path. Proposed radar includes master generator, key, coherent transmitter, antenna switch, antenna, analog-to-digital converter, system controlling antenna, two Fourier fast transform computers, unit displaying radar images, second key, control circuit, first and second phase detectors, amplitude detector, four analog- to-digital converters, delay line, unit computing parameters of radar images, unit of radar identification, range measuring system, unit of elements of linear part of receiver of summary channel, unit of elements of linear part of receiver of difference elevation angle channel, unit of elements of linear part of receiver of difference azimuthal channel, two potentiometric sensors, operator's control desk, monopulse radiator, first and second blocking circuits. Proposed design of structural circuit of radar with inverse synthetic aperture makes it feasible to achieve a number of advantages, possibility to use features of two-dimensional radar images in automatic systems of radars in combination with other features, to reduce time of building up of radar images to units of second, to generate radar images of air targets in bounds of narrow- band sounding. EFFECT: generation of two-dimensional radar images of air targets with use of radar with inverse synthetic aperture. 4 dwg
