Research on the Method of Detection and Recognition of Antisubmarine Helicopter Characters Signal

In accordance to the characters of antisubmarine helicopter radiation noise signal in air, this paper adopts Marrwavelet function to process the signal. The method of applying continuous wavelet transform to extract antisubmarinehelicopter characters signal is presented in detail in this paper. Characteristics division of complex signal and recognition accurate antisubmarine helicopter object characters are achieved successfully for utilizing the fuzzy recognition technology, which is an important theory foundation and a tool for developing weapons of striking back antisubmarine helicopter.
