METHOD OF DISCRETE NOISE CLASSIFYING AND BLANKING Russian patent published in 2016 - IPC G01S13/52 

FIELD: radar ranging and radio navigation.

SUBSTANCE: invention relates to radar ranging and can be used for radar ranging signals processing. Said technical result is achieved by method of interferences classifying and blanking, in addition to inter-frequency inter-period Doppler phase difference for unambiguous measurement of speed of objects based on two samples of observations received at two carrier frequencies assessments generation, and comparing this assessment with threshold in each range element and assigning of interfering reflection signal feature in case of this threshold not exceeding in particular range element, inter-frequency correlation factor module is generated, which is used to assess longitudinal size of classified objects and, which is not exceeding threshold, is classified as interfering signal by correlation feature, wherein after merging correlation and speed signs of interfering signal in case of their matching making decision on reflected signal blanking in given range element. At that, speed and correlation feature for clutter logical units are assigned, which matching is fixed in each range element by means of "AND" logical function.

EFFECT: higher efficiency of discrete passive jamming classification and blanking.
