Focusing on the problem that phased-array radar has some modes with complex PRI modulation patterns are difficult to accurately identify,this paper proposes a recognition method by extracting the switching rules of the PRI sequence. This method draws on the pulse template model and the dynamic programming theory of bioinformatics in gene sequence alignment,having solved the difficulty in describing some complex PRI modulation pattern and those for statistical methods in recognizing phased-array radars with mode includes a complete sequence of pulses with very short length. Simulation results show the effectiveness of the algorithm and its robustness even in the presence of interference pulses and missing pulses.
