针对现有系统误差配准算法以已知系统误差变化模型为前提条件、相应的目标状态估计易受系统误差配准结果影响等不足之处,在机载雷达与地基雷达协同防空预警体系下,对系统误差存在情况下的目标跟踪问题进行了研究,并提出了有效的地空协同防空目标抗差跟踪算法。仿真结果表明所提算法可得到无偏、稳定、有效的目标状态估计,并且相对于系统误差目标状态联合估计算法,所提算法计算量小,对系统误差变化有很强的鲁棒性,可适应实际工程应用中可能出现的异常情况,为后续决策提供稳定有效的目标信息。
Aiming at the shortcomings of the existing system error registration algorithm based on the known system error variation model and the corresponding target state estimation being easily affected by the systematic error registration results, under the air defense early warning system of airborne radar and ground-based radar, The problem of target tracking in the presence of systematic errors is studied and an effective anti-stray tracking algorithm for ground-air coordinated air defense targets is proposed. The simulation results show that the proposed algorithm can get unbiased, stable and effective target state estimation. Compared with the system error target state joint estimation algorithm, the proposed algorithm has low computational complexity and strong robustness to system error variance. Adapt to the abnormal situation that may appear in the practical engineering application, and provide the stable and effective target information for the subsequent decision-making.
