A new algorithm of localization of combined subsets of multistatic sonar system

For the purpose of improving the localization accuracy of bistatic sonar in some districts such as baseline district, side districts of transmitting and receiving stations, the most effective method is to increase the amount of the transmitting and receiving stations so that the multistatic sonar system is formed. Multistatic TOL algorithm and BOL algorithm, which are comparatively mature by far contains three measurements of one subset. Compared with the multistatic TOL, BOL algorithm and the algorithm with which the subset contains six measurements, a new algorithm which is combined of TOL and BOL algorithms for multistatic sonar has been proposed. The simulating results show that the accuracy of the new localization algorithm is much better than the other three localization methods.
