Aiming at the problem that the maneuvering behavior of unmanned target has a great influence on the calculation accuracy of firing advance point, which leads to the decrease of shooting accuracy, an adaptive Interact Multiple Model (IMM) algorithm for maneuvering target tracking is designed, based on this, a fire advance point calculation model considering target maneuvering behavior is established. The established adaptive IMM algorithm detects the target maneuver mode by calculating the target acceleration and the turning Angle rate, and the reasonable selection of target motion model is realized. The established shooting advance point calculation model uses the idea of probability weighted fusion of multiple models by IMM algorithm, realize the calculation of shooting advance point under the composite hypothesis. Simulation test shows that: The adaptive IMM algorithm further improves the tracking accuracy by selecting the model reasonably, the shooting advance point calculation model can effectively avoid the shooting deviation caused by inaccurate target movement hypothesis.
