摘要
基于时差-频差的双机无源定位以其结构简单,定位精度高而受到日益广泛的关注以及不断深入的探索和研究。针对预警机/无人机时差-频差联合定位系统,建立了定位模型,对预警机/无人机不同飞行方式下定位精度分布作了模拟仿真,得出典型场景下的定位精度分布,从而获得最佳定位精度的飞行方式。
The dual aircrafts passive location based on time difference of arrival （TDOA） and frequency difference of arrival （FDOA） is simple in structure and highly accurate in positioning. The technology is attracting more and more attention. A positioning model is established to study the AWACS- UAV joint positioning system. The distribution simulation of geometrical dilution of precision （GDOP） is conducted under different flight models of AWACS and UAVs. Simulation results under typical scenarios are ob- tained, and then the optimum flight model for positioning accuracy is defined.
