机载单站多目标定位航迹规划研究

多目标航迹规划是指侦察飞机在机载单站无源定位过程中,根据侦收到的多个目标信号方向、威胁等级和飞机本身机动能力的限制,计算出最优飞行航迹,并跟随该航迹同时完成多目标定位任务。首先建立了机载单站无源定位中的探测模型、控制模型和航迹规划模型;然后提出一种基于评价函数和扩展α法的多目标航迹规划算法;最后进行了仿真分析,仿真结果表明该方法的有效性。

Route Planning in Airborne Multi-Target Passive Location

Multi-target path planning means the aircraft figures out the optimized flight path and tracks the path to finish its multi-target location task,during the implementing of single airborne passive location.Firstly,the detection model,control model and path planning model in single airborne passive location are built.Then,the multi-target path planning algorithm based on evaluation function and extended α method is introduced.Lastly,a simulation test is designed,and the simulation results prove the effectiveness of the algorithm.
