Hit Probability Model of Terminally Guided Missiles Based on Maneuvering Noise of Targets
In the process of terminally guided rocket striking maneuvering targets,the calculation of maneuvering targets and hit probability of fire control system are the problems worthy of attention.The hitting model is established by using the shooting table fitting function and the target motion equation,and the secant method is used for iterative solution.The long-term state transition equation is derived from the discrete short-term state transition equation,from which the cumulative sum of Gaussian white noise in each short period of time is separated as a probability model for long-term prediction.For different maneuvering models,the variance of white noise in the probability model can be estimated by using the historical sampling data,and the whole variance of the model can be determined.The hit probability can be calculated according to the flight time of rockets and guidance range of terminally guidance missiles.The hit and probability of CV model,CT model,CA model and Singer model are calculated,and the accuracy of the probability model is verified by simulation.
