摘要
Abstract
A modified Markov localization algorithm is given based on the eigenvalue reference correction of the weighting matrix by accepting the idea of the ridge estimation method. The global existence of inverse of measurement errors' covari-ance matrix is realized and the singular point problem of Markov estimation algorithm in the application of bistatic sonar are settled by the algorithm. The simulation for some bistatic sonar system is done focusing on the location accuracy geometric distribution. The location accuracy of three combination patterns is analyzed quantitatively and compared. The simulation results show that compared with the localization algorithm based on optimum linear data fusion, the accuracy of locating the underwater objects and the ability of locating the region near the baseline and the two base stations are both improved greatly by the modified Markov localization algorithm. It extends the application range of redundant data combinational estimation in sonar system.关键词
