THREE-CHANNEL RADAR Russian patent published in 2014 - IPC G01S13/44 

FIELD: radio engineering, communication.

SUBSTANCE: radar includes an antenna device, three receivers, each consisting of series-connected frequency converter, intermediate frequency amplifier, optimum filter and detector, as well as an angular discriminator and a decision unit. Outputs of the antenna device are connected to inputs of corresponding frequency converters and outputs of the detectors are connected to corresponding inputs of the angular discriminator, wherein the radar also includes two dividers and a multiplier. The output of the first detector is connected to the first input of the first divider, the output of the third detector is connected to the first input of the second divider, the output of which is connected to the second inputs of the first and second dividers, the outputs of which are connected to corresponding inputs of the multiplier, and the output of the multiplier is connected to the input of the decision unit.

EFFECT: high accuracy of determining spatial characteristics of targets.
