摘　　要：卫星发射任务时,由于现有外弹道测量体制布站几何的约束,需采用脉冲雷达与少量测速雷达联合解算主动段实时外测弹道,为安全控制、实时引导和公共显示等提供重要依据。传统的综合求速、微分平滑和逐点最小二乘等实时弹道解算方法存在难以克服的缺点,通过对新引入的"UKF"算法和多种传统算法的研究、比较,结果表明,"UKF"算法是目前靶场实时外弹道解算方法中精度最高、适应性最好的算法。When satellite launch mission is executed,due to the geometric constraints of the existing trajectory measurement system, the real-time trajectory of the boost phase needs to be solved by the pulse radar in combination with an amount of velocity-measure- ment radars, which provides an important basis for the safe control, real-time guidance and public display, etc. It is difficult to overcome the shortcomings of the traditional methods such as integrating velocity, differential filtering,least squares point-by-point etc. Through studying and comparing the new UKF algorithm and a variety of traditional algorithms,the results show that the UKF algorithm is the highest accuracy and adaptive one for solving the real-time trajectory.
