Identification Method of Marine Microwave Communication Signal Based on HHT
In response to the problem of low signal resolution SNR value in current marine mi-crowave communication signal recognition,which affects recognition accuracy,HHT is intro-duced to carry out design research on marine microwave communication signal recognition methods.Calculate the attenuation of microwave communication signals at sea and determine the distribution of signal attenuation based on the calculation results.Using HHT transformation,the signal is decomposed into a series of intrinsic mode functions(IMFs),and signal classification and recognition are achieved through the output Hilbert marginal spectrum.Through compara-tive experiments,it has been proven that the application of this method significantly improves the SNR value of signal resolution,effectively promoting the improvement of recognition accu-racy.
