运动声阵列跟踪系统坐标模型研究

For studying the coupling problem between nonlinear of dynamic acoustic array tracking system and coordinate model, this paper designed the structural model of three-dimensional dynamic acoustic array, analyzed status parameters of acoustic array tracking system, and established the coordinate model of dynamic acoustic array system. Besides, it discussed the transformational relation among coordinate models, confirmed the coordinate model of export acoustic array observation information, established the Cartesian coordinate model of acoustic array and analyzed the nonlinear factors in uniform acceleration and uniform turning status. It established the modified polar coordinates model of dynamic acoustic array based on the transformation method of state space, which set a theoretical basis for further studying the tracking algorithm of dynamic acoustic array tracking system.
