Smoothing Method of The Parameters in Sidescan Sonar Data

Aimming at the low sample rate of attitude data toward that of Ping data,the paper utilized the smoothing method of Savitzky-Golay to smooth the attitude data.The result validates the method.When choosing the length of the window and degree of polynomialare analyzed,the comparability to the original data shows that the model with 2nd polynomial and 11 as its window length can make a good smooth,correlating to the original data closely.
