摘要

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 a-coustic 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.%为了研究运动声阵列跟踪系统的非线性及坐标模型之间的耦合问题,设计了三维运动声阵列的结构模型,分析了声阵列跟踪系统的状态参数；建立了运动声阵列系统的坐标模型,讨论了坐标模型之间的转换关系,确定了输出声阵列观测信息的坐标模型；以目标在匀加速及匀速转弯状态下,建立了运动声阵列笛卡尔坐标模型,分析了模型的非线性因素；基于状态空间的变换方法,建立了运动声阵列的修正极坐标模型,为进一步研究运动声阵列跟踪系统的跟踪算法奠定了理论基础.
