摘要
针对T/R-R型双基地系统工作特点,提出了一种基于点迹相关的航迹起始算法。该算法在传统逻辑法基础上,对点迹-航迹互联方法进行改进。对于落入相关波门的量测,改传统的最近距离互联为最大相关概率互联。为兼顾航迹起始的快速性,提出了相应的逻辑处理策略。计算机仿真结果表明:文中算法在杂波环境下具有较低的虚警率,在保持了传统逻辑法的快速性的同时,有效地提高了真实目标的起始概率,同时也说明双基地系统在抗杂波干扰方面有独特优势。
In terms of T/R-R bistatic system characteristic,a track initiation algorithm based on plot correlation is put forward.The correlation method of plot-track is improved on the basis of traditional logic.When the measurement fell in the association gate correlates to track,the traditional correlation rule of nearest distance will be replaced with the present one of highest correlation probability.Considering computing speed,the logic strategy is put forward.The results of computer simulation show that the presented algorithm can initiate track with low false probability,high detection probability and the same computing speed as traditional logic in clutter environment,which explains that the bistatic system have an unique advantage of anti-clutter.
