Abstract
Based on features extraction and statistics, this paper proposes a method to solve the signal recognition prob-lem in the field of space electronic countermeasure. Firstly, the received signal is coarsely classified according to the fea-tures of its instantaneous frequency and complex envelope module. Then, the signal is precisely identified based on the indi-vidual unique feature comparing with 8 given candidates. Simulation results show that when the input SNR ( Signal-to-Noise-Ratio) is greater than 11 dB, the recognition probility of the proposed method is more than 90% for those 8 candidate signal types. The complexity of the method is relatively low and is easy to be implemented in engineering.关键词
