关于双基地声呐定位及其优化算法的研究

Research on Algorithms of Localization and Opitmal Position Performance of Bistatic Sonar

由于一般的双基地系统为T/R-R型双基地声呐,发射和接收站都可以提供测量数据,于是存在冗余信息。所以,双基地声呐定位问题,实质上就是非线性系统的优化问题。为了更充分的利用冗余的观测信息,提出一种基于加权最小二乘的双基地声呐定位优化算法(WLS算法),并与传统的基于波达时间定位算法(TOL算法)进行了比较。

For most of the bistatic system is the bistatic sonar of T/R-R style, both the transmit station and the receive station provide data. Then this system has redundancy information. So the localization of bistatic sonar is actually a non-linearity optimal method, For the purpose of using the redundancy information, the weigh least square localization algorithm was provided, and also it was compared to the Time-Only-Localization algorithm.
