摘　　要：将粒子滤波应用于INS/TAN组合导航系统中。仿真证明,该滤波方法有效地克服了地形的非线性特性和惯导误差对组合导航结果的影响。We applied particle filter in the integrated INS/TAN navigation system. Simulation proved that the filter can overcome significantly the effect of nonlinearity of elevation and inertial error on navigation. But since large quantity of particles are needed to achieve a relative high accuracy, thus the real - time characteristic of the method is not so satisfied.
