| 摘 要： | 在多观测站目标被动跟踪过程中,多观测器运动轨迹对定位跟踪精度有重要影响.为提高对运动目标的跟踪精度,将目标滤波协方差的迹作为目标优化函数,提出一种基于粒子群算法(Particle Swarm Optimi-zation,PSO)的多观测器轨迹优化方法,并将轨迹优化加入运动目标被动跟踪过程中,实现了观测器自适应运动下的运...

| Abstract: | In target passive tracking system,the trajectories of multi-observers have a major impact to tracking accuracy.In order to improve tracking accuracy,a multi-observers trajectory optimization method based on PSO algorithm is proposed with the trace of filter covariance as objective optimization function.The passive tracking of moving target under adaptive motion of observers can be realized by adding the trajectory optimization into the process.Based on basic rules of bearing only passive tracking trajectory... |
