Modelling and simulation of underwater target's typical motion
In order to make the target's motion model more reasonably so as to improve detection probability of subsequent search action, according to different situations about whether target takes countermeasure or not, the target's motion can divide into three kinds, no countermeasure, countermeasure and uncertain information. Secondly, the forecast method of target's future position distribution based on three motions is explained respectively. Then, the motion model is proved validity by using simulation at last. This method will be worthful for the search tactics study to a certain extent.
