FIELD: radio technology.
SUBSTANCE: invention pertains to the receiver path of radio detection and similar systems and is designed for providing for high efficiency primary digital signal processing in real time in all modes of operation of on-board radar. The technical outcome is achieved due to that the radar receiver consists of n receiving channels, a low-pass filter, analogue-digital converter, a digital heterodyne mixing device, read-only memory and a digital adder. In each receiving channel there are two band pass filters, an attenuator, five amplifiers, a voltage divider, band elimination filter, sampling frequency generator, digital quadrature generator, two adapters and a controller.
EFFECT: increased efficiency of digital processing of radar signals on the background of noise with different spectral width.
