METHOD FOR MEASURING ANGULAR COORDINATES AND RADIO LOCATION TARGET COORDINATOR Russian patent published in 2021 - IPC G01S3/10 G01S3/32 G01S13/44 H01Q25/02 

FIELD: radio location.

SUBSTANCE: invention relates to radio location and can be used in the angular target tracking channels of radio location stations and missile coordinators. In the method for measuring the angular coordinates of the target, the equal-signal direction of the antenna is formed, the mismatch signal between the direction to the target and the equal-signal direction is isolated, the position of the equal-signal direction of the antenna is changed by moving the antenna in the direction of reducing of the mismatch signal, and the angular coordinates of the target are formed according to the position of the antenna. The zero direction of the difference channels is therein formed equal to the angular dimensions of the target. To implement the method, the radio location target coordinator comprises the antenna elevation angle channel, the antenna azimuth channel, and the reference signal channel. The elevation angle channel and the azimuth channel of the antenna have two antenna irradiators, a subtractor, a mixer, a limiter amplifier, a phase detector, a power amplifier and an antenna tracking drive, respectively. The reference signal channel has a summing apparatus, a mixer, an intermediate frequency amplifier, a limit threshold control circuit, and a heterodyne.

EFFECT: increasing the accuracy of measuring the angular coordinates of the target.
