摘要 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。 A method for estimating the initial track state in the netted passive sensor system is presented, which obtains the initial track state using the Levenberg-Marquart algorithm and takes the Cramer-Rao lower bound as the variance of the state estimation errors approximately. The methods for obtaining global optimal solution and removing the solution obtained under conditions of unobservability are investigated. Simulation results show the method presented in this paper is effective and valid.
