METHOD FOR ENERGY REVEAL OF RADIO-SIGNALS AT EFFECT OF ACTIVE MASKING INTERFERENCES

摘要

Method for energy reveal of radio-signals at effect of active masking interferences is based on check of statistic hypotheses by criterion of minimum of average risk and uses energy likelihood ratio. To determine the threshold of decision making on reveal of target at continuous determination of energy likelihood ratio and effect of active masking noises the method includes procedure of identification of interval of effect of those through analysis of additional energy likelihood ratio that is defined by ratio of continuous evaluation of energy of mix of internal noise and active interference at interval of analysis equal to duration of signal to values averaged in several intervals of analysis of energy of noise of the previous period of sequence of radio signals at apriory absence of masking active interferences and radiosignals and comparison of energy likelihood ratio in each interval of analysis to threshold of decision making, this is determined by Neuman-Pirson criterion, with making decision on the beginning (end) of effect of active interferences at presence of excess of threshold of reveal (absence of excess of reveal threshold) by criterion “m of m” intervals of analysis in succession.
