摘要
采用方位角变化率最大作为优化准则,分析了二维只测角无源定位中单观测器的运动轨迹优化问题。首先给出了在该准则下最优轨迹的一种几何求解方法,得到定位固定目标和运动目标时观测器最优轨迹的解,然后仿真对比了采用该方法和其它方法对匀速运动目标跟踪的效果,最后给出了仿真结论。
Adopting maximizing azimuth changing rate as the optimization rule, the optimization of singleobserver trajectory in two-dimension bearing-only system of passive location is analyzed. First, a geometrical method to calculate optimized trajectory is advanced under the rule, and the optimized trajectory is figured out when single-observer locates a fixed target or a moving target. Second, the tracking effect under this way and others ones while the observer is tracking a target of constant-speed linear moving is simulated. At last, the simulation conclusion is given.
