摘要
单站无源定位跟踪技术具有隐蔽性强、设备简单、系统相对独立等优点。定位收敛速度和稳定度是该技术实际应用的关键,通过研究利用频域和空域测量信息对运动辐射源的单站无源定位跟踪技术,分别提出了两种定位跟踪算法。为比较算法性能,推导了该定位跟踪问题的克拉美 罗下限,并利用计算机仿真给出了不同算法的跟踪误差几何分布(GDTE)。仿真结果证明了两种算法都具有很好的实用性。
Single-observer passive location and tracking (SOPLaT) technology has many merits, such as simpleequipment and independent system. The location convergence speed and stability are the key aspects of SOPLaT. Based on the study of SOPLaT of the moving emitter using frequency and spatial measurements, two location and tracking algorithms are presented. To compare the performances of these algorithms, the Cramer-Rao lower bound of the location problem is given. The geometrical distribution of tracking error(GDTE) of the algorithms are also given through the computer simulation. The results show that both algorithms are of great practicability.\;
