Xi Chen · Jisuanji fangzhen · 2007
With the improvement of the precision of acoustic measuring velocity,acoustic Doppler velocity log has been used in the navigation of some kinds of carrier.According to the requirement of simulation of DVL,the theory of measuring velocity was studied.At the same time,the theory of vector synthesized and coordinate transformed were studied.The formula of depth and velocity simulation were given.Synchronously,a module of A/D and D/A based on PXI was designed.The experiment proved the validity and feasibility of the simulating method.The method is suitable to different kinds of DVL.Simulating circuit is suitable to other similar engineering project.
