METHOD FOR RADAR DETECTION OF SIGNALS REFLECTED FROM TARGETS, AND DEVICE FOR REALISING SAID METHOD Russian patent published in 2011 - IPC G01S13/04 

FIELD: physics.

SUBSTANCE: in the inventions, after matched filtering, a final decision on the received signal which exceeds the detection threshold is made after additional analysis, where the degree of mismatch between the received signal and the matched filter is evaluated. For range samples in which the detection threshold has been exceeded, the ratio of the value of the signal envelope before matched filtering, delayed by signal processing time during matched filtering, to the value of the signal envelope after matched filtering is determined. The obtained ratio is compared with a given threshold value established based on the acceptable mismatch of the received signal which is reflected from the target. A decision is made on detection of the signal which is reflected from the target if the said threshold value was not exceeded.

EFFECT: high protection of radar stations from pulse interference in form of high-power mismatched signals.
