Study on the Coordinates Model for Dynamic Acoustic Array Tracking System
To solve the coupling problem of different coordinate system when tracking the acoustic target by the dynamic acoustic array. The polyhedral acoustic array system applying in the motion carrier combined by four acoustical sensors was designed in the paper. Considering the practical application of tracking the two-dimensional motion target by the threedimensional dynamic acoustic array. Establish the coordinate model of dynamic acoustic array carrier of 6 degrees of freedom. Discuss the exchange relationship in each coordinate model, to determine the coordinate model of output signal of dynamic acoustic array. And then set the Cartesian tracking coordinates model of two-dimensional acoustical tracking in the dynamic acoustic array tracking system, basing on the uniform acceleration and uniform turning motion of two-dimensional acoustic target, separately discussing the application of Cartesian tracking coordinates model and correction polar coordinates tracking model in the dynamic acoustic array tracking system. To ensure the suitable coordinate system of the dynamic acoustic array tracking system. And at the same time set a theoretical basis on the further study about the tracking algorithm of dynamic acoustic array tracking system.
