摘要
Abstract
The intra⁃pulse modulation recognition of radar signal is an important component of radar reconnaissance signal processing. The complicated signal environment makes the modulation recognition of radar signal more difficult. According to the obvious difference between frequency modulation(FM)signal and phase modulation signal at 3⁃dB bandwidth,the rough classi⁃fication and recognition between the two signals can be realized. And then the signal instantaneous frequency is extracted based on improved instantaneous self⁃correlation algorithm to detailedly classify and recognize the FSK signal and PSK signal. Under the conditions of different signal to noise ratio(SNR),the instantaneous self⁃correlation algorithm was verified by simulation ex⁃periment. In comparison with the traditional algorithm,the new signal recognition algorithm has higher efficiency and accuracy.关键词
