The Application of Incoherent Correlation Detection Method in Stochastic Resonance Beam-forming

摘要：

At first, the basic principle and numerical method of bi-stable stochastic resonance (SR) system was described and the SR beam-forming method with single-frequency signal was studied to verify that the SR system could get a gain to the array element, but not with the Correlation Detection method (matched filter) be used together. Secondly, in order to use a detection algorithm, frequency-hopping signal pulse and incoherent correlation detection method were taken in this paper, which identified SR-based incoherent detection method. Finally, SRbased incoherent detection method and conventional incoherent detection method were contrasted. The simulation showed more side-lobe suppression in SR based method, and the method could enhance the target intensity effectively and be more availability than conventional incoherent in reverberation suppression was proven by the processing of sea trial data. Therefore, SR-based detection method could be used in the target detection or imaging in the background of reverberation.
