摘要
对于水声定位系统来说,发射信标特性是影响其性能的最重要因素之一.因此,对信标体制进行深入研究,并设计更加合理的信标体制十分重要.目前常用的信标体制主要依靠各种调频信号与单频信号的组合,甚至只依靠单频信号的频率来完成多目标定位,具有可定位目标数目少、定位精度低、硬件结构复杂等问题.为了克服以上问题,论文从信标体制入手,提出了一种基于相位编码的全新的水声定位信标.经仿真验证,与目前常用的信标体制相比,该信标体制具有更高的测量精度和多目标分辨能力,并可显著简化系统硬件复杂度.
Abstract
For the acoustic positioning system,the characteristic of the beacon is one of the most important factors that affect its performance.Therefore,it is important to conduct an in-depth study of the beacon system and design a more reasonable beacon system.The commonly used beacon system mainly relies on the combination of various FM signals and CW signals,even only on the frequency of CW signals to achieve multi-target localization,which has the issues of a small number of locatable targets,low local-ization accuracy,and complex hardware structure.To overcome such problems,this paper proposes a novel acoustic positioning bea-con which is based on the phased code.Based on simulations,it has been verified that the proposed beacon system provides higher accuracy and multi-target resolution capability.Furthermore,it also can simplify the system hardware complexity significantly.
