摘要
为了改善双基地声纳在某些区域(如基线区、发射和接收站的侧边区)定位性能,最有效的方法就是增加发射和接收站的数量,形成多基地声纳系统。而目前较成熟的多基地算法的测量子集都包含3个测量量,基于此提出了一种将基于波达时间的多基地声纳定位算法(TOL)和基于方位测量的多基地声纳定位算法(BOL)的测量子集进行联合估计,并将这种新算法与包含6个测量量的测量子集的多基地声纳定位算法做比较。仿真结果证明,提出的联合测量子集定位算法的定位精度要比多基地TOL、BOL以及多个测量的多基地声纳定位算法的定位精度都要高。
To improve the localization accuracy of bistatic sonar in such districts as baseline district, and side districts of trans- mitting and receiving stations, the most effective method is to increase the number of transmitting and receiving stations, which forms a multistatic sonar system. The mature algorithms for multistatic sonar system are the multistatic time-only localization （TOL） algorithm and the muhistatic bearing-only localization （BOL） algorithm, which contain three measurements in one sub- set. This paper proposes a new algorithm by combining multistatic TOL algorithm and multistatic BOL algorithm for multistatic so- nar system. The simulation results show that the proposed localization algorithm exhibits highest accuracy compared with the mul- tistatic TOL algorithm, the muhistatic BOL algorithm and the algorithm whose subset contains six measurements.
