Abstract :
Recently the more complex conditions of radar exploitation are connected with saturation of some areas with many radio engineering systems creating complex interference situation. The purpose of this work is: an analysis and estimation of immunity of the multi-channel correlator under matched processing of sequences wideband noise pulses (NP) in condition of the influence of the active continuous interferences (CI) of different types and parameters using criterion of immunity on signal level; a selection of dangerous types of such CI and revision of the conditions of their setting up; a revealing the peculiarities and advantage of the using the noise signal of the given structure with a large time-bandwidth product and small power spectrum density for ensuring of immunity of its correlating processing in condition of the active continuous interferences.
