基于点航迹质量评估的雷达目标联合检测跟踪方法
|
摘要
提出一种基于点航迹质量评估的联合检测跟踪方法。通过检测器和点迹提取器预处理得到待确认点迹,并在点迹提取的同时基于凝聚为同一点迹的多维回波数据特性计算点迹质量,然后采用基于动态规划的多周期联合检测方法实现对多周期待确认点迹的联合检测跟踪处理,提取目标信息,通过两组实测数据的处理验证了该方法的有效性。该算法在不改变经典雷达信息处理架构的条件下提高了复杂背景下目标发现能力和虚假抑制能力。
A joint target detection and tracking method based on Plot-Track Quality Evaluation(PTQE-D&T) is proposed. Firstly, a set of candidate plots is extracted from the Detector and Plot-Extractor, where the plot quality is calculated simultaneously based on multi-dimensional echoesconstituting the plot. Then, a multi-cycle joint target detection and tracking based on dynamic pro-gramming( DP) is utilized to realize joint detection and tracking of the multi-cycle unconfirmedplots as well as target information extraction. The effectiveness of the proposed method is verified bythe processing results of two measured data. Moreover, without changing the conventional radar dataprocessing architecture, the algorithm improves the ability of target detection and false suppression incomplex background.
