A Low Intercepted Signal Recognition Algorithm Based on PFRFT
摘要
Abstract
Aiming at modulation recognition problem for low probability of intercept radar signals ,a new type of modu‐lation recognition algorithm is put forward to complete the discriminator of eight kinds of LPI signals ,including LFM ,BPSK , 2FSK ,Frank/P1/P2/P3/P4code .The preliminary classification is completed according to the presence or absence of signal frequency modulation slope through PFRFT .And utilization of primary and secondary domain Fractional ridge line ,and the power spectrum estimation is used to complete the automatic classification of the signal .The flow chart and identify specific steps of classification algorithms are given .Simulation experiment shows that the algorithm has good recognition results and good effectiveness and feasibility .关键词
