中文摘要：

时敏目标具有时间约束严格，作战决策随机性强，作战行动并行，信息交互要求高等特性，需要具有快速探测和打击的能力才能有效应对时敏目标的威胁。本文针对时敏目标的特点，采用多种平台对其进行探测和跟踪；鉴于对偏差配准的实时性要求，提出一种基于平方根中心差分滤波的边配准边跟踪方法，该算法具有较高的精度和数值稳定性，仿真结果验证了其有效性。

英文摘要：

Time-critical targets with strict time constraints and operational decision-making random combat operations in parallel, information exchange requirements of quality characteristics, so rapid detection and strike ability is needed to respond effectively to sensitive target threat. According to the characteristics of time-critical targets, multiple platforms are used for its detection and tracking. According to real-time requirements, the algorithm with better accuracy and numerical stability for simultaneously deviation registration and target tracking based on central difference Kalman filter is raised. Simulation results show that the algorithm has a good performance and it further demonstrates the algorithm is effective.
