基于矢量信号处理的水下目标定位和跟踪设计

通过仿真实验,提出基于矢量信号处理的水下目标定位和跟踪设计.以传统的三元对称阵和单站纯方位目标被动测距方法为基础,根据被动测向得到的目标方位信息,利用三个矢量传感器阵元组成联合测量阵,进行水下目标的被动定位和轨迹跟踪.考虑现场实际测量情况,对目标测向得到的方向信号就时间延迟进行补偿,提高了水下目标被动定位和跟踪的精度及可靠性.仿真实验说明,设计实际操作性好,能够对目标进行更加理想的跟踪定位.

Target Localization and Tracking Design Based on Vector Signal Process

An underwater target passive localization and tracking design based on vector signal process is presented. It is based on two conditional target passive ranging methods of three - element symmetrical measuring array and single platform beating - only target states estimation. According to the bearing estimation of the underwater target acquired by the passive goniometry, three vector sensor elements are combined into an united measuring array. For more accurate and reliable localization of the target, the time delay estimation of the measured direction signals of the target is compensated. Simulation results show that this design is easy to implement and can realize better target localization and tracking.
