MULTI-CHANNEL CORRELATED-FILTERING RECEIVING DEVICE WITH DOUBLE LINK SELECTION OF MOVING TARGETS (ALTERNATIVES) Russian patent published in 2008 - IPC G01S13/526 

FIELD: physics.

SUBSTANCE: invention can be used in radar systems, which use probe signals with a combed spectrum. The multi-channel correlated-filtering receiving device with double-link selection of moving targets consists of, serially connected selection and storage device, double-link selector of moving targets of the compensated type, modulator, multi-channel device for correlated-filtering selection of received signals from a pulse Doppler radar, as well as a weight function generator, the output of which is connected to the second input of the modulator. A digital or discrete canonical recursive low frequency filter is used in the compensating channel of the double-link selector of moving targets. This filter has a repeating amplitude-frequency response, and at frequencies F multiples of 1/T, where T is the period of repetition of the pulses of the quasicontinuous signal, which turns into a combed band. The use of such a filter provides for suppression of radio pulses of noise at intermediate frequencies.

EFFECT: increased stability of operation and wider range of functional capabilities.
