摘要: 提出了一种基于最小二乘估计的电影经纬仪交会测量算法.充分利用3台经纬仪测得的冗余数据,用迭代算法求得运动目标在任一时刻的空间位置,且避免了目前的直接算法中两套公式切换时机不易掌握的问题.理论分析和在新的布站方案下的数值模拟结果表明,该方法具有计算精度高、收敛速度快的优点.相对于目前采用的直接算法,可较好地改变对飞行目标的测试精度.Abstract: A method based on the least square estimation for movie transit rendezvous survey is proposed. In conventional direct algorithm. It is not easy to control the switching time of two equation. This new method is an iterative algorithm, it can obtain the moving object' spatial location at anytime used the redundant data of three transit and avoid the question of two equation'switch. Theoretical analyses and numeric simulations in the new choice of stations have shown that this method possesses the advantages in computation and the fast convergence rate.Compare with the conventional direct method.It can improves the measure precision of radar etc.
