基于多处理器的水下潜器定位系统设计

Design of submarine vehicle positioning system based on multi-processors

设计了一种对水下潜器实时定位的微处理系统,采用宽带超短基线定位方法,通过在潜器上加装声学传感器来实现对潜器的实时定位。为了实时接收处理声学传感器发出的定位信号,设计了基于多DSP的数字信号处理微系统。该系统采用3片高性能TMS320C6416处理器结合一片FPGA芯片,完成对水下目标的实时数据采集和定位解算功能。试验结果表明:该定位系统对目标的轨迹跟踪误差小于1%斜距误差,具有良好的定位性能。

A micro processing system is developed for positioning the submarine vehicles in real time, which adopts wide-band ultra-short base line（USBL）positioning method to track the target of interest through onboard sensors in the vehicles. In order to satisfy the real-time performance, a micro system based on multi-DSP is designed to receive and process signals. This system make use of three high performance TMS320C6416 chips and one FPGA chip to acquire data and solve the target position for submarine target. The trial results have indicated that the system precision of the target track in less than 1% of slant range error, which has excellent positioning performance.
