Abstract

Speckle suppression methods can be roughly divided into three categories: the first one is based on the statistical characteristics of a speckle, the second one uses multiple echoes measured in the different frequency bands, and the third one uses multiple echoes measured from the different directions respectively. However, each of those has shortcomings to be improved. On the other hand, the research in the engineering application of the mechanism of stochastic resonance has been advanced variously. Stochastic resonance can be viewed as a noise-induced enhancement of the response of a nonlinear system to a weak input signal, and naturally appears in many neural dynamics processes. In this study, we study a speckle suppression method based on the scheme of stochastic resonance.
