摘要
末制导火箭弹对机动目标打击过程中,火控系统对机动目标的解算及命中概率是值得关注的问题。用射表拟合函数与目标运动方程联立建立解命中模型,并采用弦截法迭代求解。用离散的短时状态转移方程推导出长时期状态转移方程,从中分离出各短时间段内的高斯白噪声的累积和作为长期预测的概率模型。针对不同机动模型,用历史采样数据估计概率模型中白噪声的方差,从而可确定模型整体方差,并根据火箭弹飞行时间及末制导弹制导范围可计算命中概率。对CV模型、CT模型、CA模型和singer模型进行了解命中和概率计算,通过仿真验证了概率模型的准确性。
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.
