The target motion is described by the model of discretestate, discrete-time markov chain. According to hospitability map of bathygram, the target's probabilistic state transition matrix is figured out. On the basis of target's initial distribution and state transition matrix, unmanned underwater vehicle continuously estimates and updates the the target's present state, uses a new greedy algorithm to get the optimum searching paths. This new searching method is proved by the results of simulation in the end, and is worthful for the tactics of unmanned underwater vehicle.
