本文提出了一种估计被动传感器系统航迹初始状态的方法,该方法采用Levenbe唱一MarqlJan算法求解航迹初始状态,将cr锄er.Ra0下界近似作为状态估计误差的方差。文中还对如何获取全局最优解和如何排除在不可观测条件下得到的全局最优解进行了探讨。仿真实验结果验证了本文方法的有效性、合理性。
This paper presents a method to estimate the initial state of the track of the passive sensor system. The method uses Levenbe Sing-MarqlJan algorithm to solve the initial state of the track, and uses the lower bound of cr hoe er.Ra0 as the variance of the state estimation error. The paper also discusses how to get the global optimal solution and how to get rid of the global optimal solution obtained under the condition of unobservable condition. The simulation results verify the effectiveness and rationality of the proposed method.
