Method for suppression of passive noise is in fact that one performs coherent reception of radio-location signals at that level of received signal is decreased, if it exceeds dynamical range of receiving system of radar system, with unfaltering received signals by Doppler frequency, with calculation of average level of unfiltered signals by range, comparison of unfiltered signals with threshold by energy and blanking signals that have exceeded the threshold if radial velocity of those is smaller than set one. Threshold by energy is formed through multiplication of average by range level of unfiltered signals by variable coefficient value of which is increased with decrease of range to objects revealed. |
