Designation of backscattering optical signal of ship wake

In order to obtain accurate information of ship wake and the detection range auto-adaptively,based on the characteristics of the backscattering optical wake signal,the minimum screening method was used to process the baekscattering signal.After anti-ground noise,based on the criterion of least mean-squared error,with the wake flow backseattering optical signal subtracting the water baekscattering optical signal,the pure wake signal was obtained.A simple model of the pure wake signal was built,based on which the relevant information of the wake thickness was obtained.The results are helpful to judge and identify the wake character information.
