Multi-component Emitter Signal Analysis Method Based on Reassigned S-method

  • Received Date: 16 May 2007

  • To effectively detect and recognize multi-component emitter signals,a multi-component emitter signal analysis method based on the reassigned S-method(RSM) was proposed.To suppress the serious cross-terms of the Wigner-Ville distribution and cut down its high computational complexity,RSM was adopted to analyze dense and overlapping emitter signals.The hardware implementation and computional complexity analysis of its algorithm were given.The proposed method can process effectively linear and non-linear frequency-modulated signals,and its algorithm is simple and easy to implement.Experimental results on complex multi-component emitter signals show that the proposed method is a good approach to analyze multi-component emitter signals because of the advantages of its high time-frequency resolution,removing cross-terms,and strong noise-suppression ability over the Wigner-Ville distribution and the S-method.
