Design for underwater platform´s attitude data acquisition system based on software radio technology

That the underwater platform rocks constantly in the water will lead to serious bias in the long-range detection to a target. Therefore it is necessary to track and predict the attitude of the swaying platform accurately. This paper introduced an attitude data acquisition system which uses the principle of software radio technology, and can operate steadily for a long time based on a low power electronic compass. Meanwhile, the function that controls the sampling model in the dynamic condition has been verified correctly with the prototype of data acquisition system.
