中文摘要:
针对实际情况下机载预警雷达虚警多、易掉点和俯仰角误差大从而导致目标航迹起始和跟踪困难的问题,以WGS-84坐标系为框架,提出机载预警雷达量测关联地面雷达航迹进行目标跟踪的PDA-UCMKF新算法,推导PDA-UCMKF方法的状态更新和误差协方差更新方程,实现了机载预警雷达对中高空目标的快速跟踪.在杂波环境下仿真对比NN-UCMKF和PDA-UCMKF方法的关联和跟踪效果,表明PDA-UCMKF方法有效、可靠且易于工程实现.
English Summary:
To solve the problems of false alarms, large elevation error and losing detections in airborne early warning radar, a new tracking method was proposed based on air-ground PDA-UCMKF in WGS-84 coordinate system for airborne early warning radar to improve the track initiation and target tracking. A state and covariance update formula was deduced in WGS-84 for airborne early warning radar to achieve target tracking quickly in high altitude. Compared with NN-UCMKF method, the association and tracking effects of PDA-UCMKF were simulated in mixed wave condition. The results show the efficiency and reliability of PDA-UCMKF method, and easy to implement in engineering.
