Abstract
Aiming at the problem of low automatic recognition rate and less types in electronic reconnaissance system, an effective method for automatic recognition of intra-pulse modulation type based on fusion of Singular Value Decomposition(SVD) and Principal Component Analysis(PCA) was put forward. After SVD and PCA to Time Frequency Distribution(TFD) image of the radar signal, the method fused eigenvectors based on certain fusion rules to recognize radar signal. The results of simulation indicate that the method based on fusion of SVD and PCA is of higher correct recognition more rate than 90% under the low SNR(4 dB). In the meantime, the structure of classifier is simple and not sensitive to noise.关键词
