针对开窗干扰隐蔽性强,目标检测概率低的特点,文中提出了利用接收机检测门限判断干扰的方法以及基于TOMHT的目标跟踪方法,同时研究了不同雷达探测区域内目标的航迹管理。仿真表明,此方法具有较强的适应性,实现了开窗干扰下的目标跟踪,对开窗干扰下目标跟踪具有一定的理论参考意义和实际应用价值。

In the presence of smart noise jamming, the target detection probability decreases and the jamming have strong conceal-ment ability. Aiming at this complicatedness, the TOMHT tracking algorithm was accomplished. At first, smart noise jammingwas discriminated by receiver detection threshold. Later measurements were used to estimate target state by TOMHT algorithm.Track management in different region was also considered. The simulation results show that this algorithm presented by this paperhas adaptability and good performance for smart noise jamming and has value for engineering application.
