Results of Laboratory Test of Immunity of Correlator Affected by Active Continuous Interferences at the Processing of Wideband Noise Pulses Sequences

Works concern to computer modeling of immunity of noise and LFM radars affected by single-frequency interference that is its influence on a form of output correlation effect depending on time of accumulation. The different influence of single-frequency interference is examined for both noise and LFM-signals as well as SAR-image. Advantage of application of matched correlating processing of a noise signal is quality shown for neutralization of influence of single-frequency interferences by means of increase of accumulation time. The presented experimental investigation of immunity of noise radar affected by wideband or/and single-frequency interference. The aim of the presented work is: estimation of immunity of correlator matched with a noise pulse under influence of active (mutual and intentional) continuous interferences with application of local criterion of immunity at signal level; detection of the decorrelating factors bringing with a real correlator.
