[0087] The MM-PPHDF method for improving the search strategy proposed by the present invention will be described in detail below in conjunction with the accompanying drawings.
[0088] Without loss of generality, a two-dimensional simulation scene is set, the monitoring area S=[-60km, 60km]×[-60km, 60km], and the total simulation time K=50s. It is assumed that the target obeys one of the following three motion models: uniform linear motion mode, clockwise coordinate rotation mode and counterclockwise coordinate rotation mode, and the probability of the initial motion mode of the target It can be freely converted between 3 motion modes, and the conversion between various motion models can be described as a 3-state first-order Markov chain, and the mode probability transition matrix
