Measurement for Missile-target Miss Distance Based on 3D Rectilinear Motion with Constant Acceleration
一种基于三维匀加速直线运动的导弹与目标脱靶量测量方法

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.
