The Technique of Anti-interference Used in Data Acquisition of Bathymetric Survey

Because of effect of surroundings and the data acquisition s ystem, the re are some kinds of interference and noise in data acquisition of bathymetric s urvey, which makes sounding less reliable and accurate. In consideration of prac tical work, usual kinds of interference are analyzed in this paper, some measure s to restrain and weaken the interference are studied, and many anti-interferenc e techniques used in data acquisition of bathymetric survey are given.
