Optimal maneuver trajectories of the observer platform in passive localization system
被动目标定位系统观测平台的最优机动轨迹

The optimal trajectory of the observer platform in passive localization system is analyzed. By maximizing the determinant of the Fisher information matrix(FIM), we develop a novel instant maneuver control strategy. We also give the equations for the two optimal trajectories which are theoretically proved to be existing. It is noted that the optimal maneuver thus obtained is optimal at any instant, not only at the end point of the observation. The operation of the maneuver control sequence is depicted visually by geometry. Besides considering the maximum variation rate of the angle, the proposed method takes into account the effects of the range and e bearings, and makes a compromise between them. Numerical simulations show that more information can be observed from the optimal maneuver trajectory than that from other traditional ones.
