摘　　要：针对弹道导弹突防过程中的有源假目标欺骗干扰,提出了一种基于弹道平面性的有源假目标鉴别算法。分析了自由段真目标和有源假目标的轨迹几何特性,真目标轨迹的所有点迹的地心矢径都在同一个平面内,而有源假目标的轨迹上所有点迹的地心矢径不在同一个平面内。利用真假目标航迹的这种平面性差异,提出了一种基于滤波航迹拟合平面的自适应双门限鉴别算法。计算机仿真实验验证了本文所提的鉴别算法的有效性和可行性。The discrimination problem of active decoy and radar target was studied based on the ballistic trajectory＇s planarity in the background of missile defense. The trajectory＇s geometrical feature was analyzed for both the real target and false target in the midcourse. All the radius vectors from the center of earth to the trajectory points are in the same plane for the real target, while they are not for the false target. Using the planarity difference, an adaptive discrimination algorithm with double threshold was proposed based on the filtered track＇s fitted plane. The computer simulation was carried out. The feasibility and validity of the proposed algorithm were verified by the simulation results.
