| 摘 要： | 本文提出了一种对雷达测量数据进行处理而得到导弹与目标间脱靶量的算法，该算法在建立精确的空间运动模型的基础上，对雷达数据处理所得的弹目之间的距离平方进行非线性拟合，进而对拟合曲线求导并进行零点搜索得到脱靶时刻，之后在三维方向上再次拟合并内插得到矢量脱靶量和标量脱靶量。仿真实验表明，该算法具有很好的精度和稳定性，可在实际应用中提供有效数据。

| Abstract: | An algorithm for measuring missile-target miss distance using radar data processing is presented. Based on accurate three-dimensional motion mode, the curve of square-distance translated from radar data between missile and target is fitted with nonlinear method, and differentiated and sought on the zero point to confirm the miss time. The vector miss distance and scalar miss distance can be obtained by fitting three-dimensional motion function and substituting the miss time into that. The simulation experiment shows that the algorithm has good accuracy and stability, which can apply valid result for practical applying. |
