Abstract
Aiming at the problems that point-mass filter(PMF) algorithm is of great computation, slow convergence and initial error sensitivity, a combination scheme of terrain contour matching(TERCOM) algorithm and PMF algorithm is proposed. Firstly, the influence of search area resolution on the PMF algorithm is analyzed. Then a combination scheme taking TERCOM for coarse matching and PMF for fine matching is simulated and compared with the other scheme taking PMF for coarse matching and TERCOM for fine matching. The result shows the former scheme behaves better in convergence and positioning accuracy for both rough and flat terrains with a good engineering application.关键词
