摘　　要：围绕被动雷达站组网对无人机跟踪定位问题,利用时差定位模型实现无人机的定位跟踪研究。通过几何精度稀释(GDOP)计算分析,计算雷达站接收信号的时差,从而计算每个时差无人机的位置,然后分别从时间测量值误差、位置误差等方面分析这些因素对于无人机定位的影响。根据4个雷达站时差数据,解算出无人机机位置坐标,给出了无人机飞行轨迹;考虑被动雷达时间测量误差、站址测量误差,建立GDOP定位误差模型,通过计算出无人机定位误差,证明其定位精度满足工程需求。Research on the tracking and tracking of unmanned aerial vehicles using a time difference of arrival localization model,focusing on the problem of passive radar station networking.By using Geometric Dilution of Precision(GDOP)calculation and analysis,the time difference of the received signal from the radar station is calculated,and the position of each time difference drone is calculated.Then,the impact of these factors on drone positioning is analyzed from the aspects of time measurement value error,position error,etc.Based on the time difference data of four radar stations,the position coordinates of the drone were calculated,and the flight trajectory of the drone was provided.Considering the passive radar time measurement error and station location measurement error,a GDOP positioning error model is established.By calculating the drone positioning error(see Table 2),it is proven that its positioning accuracy meets the engineering requirements.
