摘要
增大探测距离、快速精确跟踪是高频地波雷达探测飞行小目标所面临的主要困难.本文提出了高频地波雷达飞行小目标跟踪(AWATT)系统.该系统主要包括自适应改进Hough变换(AMHT)航迹起始、双门限快速联合概率数据关联(DTF-JPDA)以及间接测量(IM)精度改善,分别解决了低信噪比条件下,对飞行小目标的提早预警、快速关联以及精确跟踪问题.实验结果验证了该系统在跟踪预警飞行小目标中的有效性.
Increase of detection range and fast precision tracking are main difficulties in weak aerial target detection for High Frequency Surface Wave Radar （HFSWR） .An Anti-Weak Aerial Targets Tracking （AWATT） system for HFSWR is proposed.It consists mainly of Adaptive Modified Hough Transform （AMHT） track initiator, Double Threshold Fast Joint Probabilistie Data Association （DTF-JPDA） and Indirect Measurement （IM） accuracy-improving part. On the condition of low signal-to-noise ratio （SNR）, it solves the problems of earlier warning, fast data association and precision tracking. The experimental results indicate the validity of it in tracking and early wanting weak aerial targets.
