RADAR STATION WITH DIGITAL FILTER Russian patent published in 2014 - IPC G01S13/524 

FIELD: radio engineering, communication.

SUBSTANCE: radar station comprises a transmitter, the input of which is connected to the output of a coherent oscillator, a receiver, the output of which is connected to the signal input of a phase quantiser, digital non-coherent filters, outputs of which are connected to inputs of a digital resolver, a synchroniser, the output of which is connected to clock inputs of the phase quantiser, the digital resolver, the digital non-coherent filters of the receiver and the transmitter. The radar station also includes N digital phase changers, N-1 phase quantisers and a digital phase changer control unit, wherein the output of the coherent oscillator is connected to signal inputs of the digital phase changers, control inputs thereof are connected to corresponding outputs of the digital phase changer control unit, outputs of the digital phase changers are connected to signal inputs of corresponding phase quantisers, outputs of which are connected to inputs of corresponding digital non-coherent filters, and the clock inputs of the phase quantisers and the digital phase changer control unit are connected to the synchroniser.

EFFECT: high speed of processing echo signal information.
