| 摘 要： | 对天基信息支援下的地基预警雷达搜索空域优化进行了研究。建立了战术弹道导弹（TBM）的运动模型和预警卫星的测量模型,用Unscented卡尔曼滤波（UKF）算法对TBM的运动状态进行滤波估计,并结合解二体运动方程确定搜索空域的中心位置,根据误差传播公式建立了搜索空域半径的确定模型。仿真结果表明：该优化方法符合反TBM预警的实际,可明显提高地基预警雷达对TBM的发现概率。

| Abstract: | The search volume of ground radar under space-based information support was discussed in this paper.The motion model of TBM and the measuring model of warning satellite were established.The TBM motion state was filtered by UKF algorithm.The center of search volume was determined based on the two-body motion equation.The radius was put forward by the error spread formula.The simulation results showed that this method was in accordance with the fact of anti-TBM warning,which could improve the detection probab... |
