摘要
为解决水下集群多目标定位问题,提出一种基于多频率信标时延估计的多元阵定位方法,文中首先对多目标定位系统进行总体设计,随后开展了基于4元阵的定位原理研究,并且进行了系统的误差分析、目标测速方法研究;开展了基于Notch数字滤波器的多目标水声信号处理方法,该方法在FPGA嵌入式系统上运行,适合多通道的并行处理.最后通过水布垭湖上试验验证了系统的功能、性能指标.试验数据表明该系统可在4km范围内对水下多目标进行实时定位跟踪.
Abstract
In order to solve the problem of multi-target positioning in underwater vehicles,A multi array positioning method based on multi frequency beacon time delay estimation was proposed.The overall design of the multi-target position-ing system was first introduced in the article,followed by the research on the positioning principle based on a 4-element ar-ray,and the systematic error analysis and target velocity measurement method research are carried out;This paper intro-duces a multi-target underwater acoustic signal processing method based on Notch digital filters,which runs on FPGA em-bedded systems and was suitable for multi-channel parallel processing.Finally,the functionality and performance indicators of the system were verified through experiments on Shuibuya Lake.The experimental data shows that the system can per-form real-time positioning and tracking of multiple underwater targets within a certain water area.
