SNR-Based Weighted Fusion Algorithm of Multiple Sub-Band DEMON Spectrum

摘要：

　　By using the advantages of two classic line spectrum extraction methods,one rule was given for the determination of line spectrum,which could be used to extract the line spectrum.Based on the DEMON spectrum SNR of different bands,one fusion algorithm of multiple-band modulation information was proposed.Large numbers of samples from ship radiated noise were tested to validate the algorithm,and the results show that this method will improve SNR and harmonic structure of DEMON spectrums,which is highly advantageous for target recognition.
