摘要
Abstract
There was no explicit understanding about ADCP' s velocity measuring accuracy. This paper compared two ships' velocities which were mersured by ADCP-track and GPS, and then the paper analyzed the ADCP' s velocity measuring accuracy under different ship velocities. The paper draws up the velocity measuring errors of the two types of RDI ADCP based on the method of straight line matching. The result indicates that the 38kHz ADCP' s velocity measuring accuracy was better and it is not influenced by ship-velocity; while the 300kHz ADCP' s track-velocity is faster than GPS-velocity all the time, and the error is increasing linearly with ship-velocity.关键词
