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。
Due to its simple structure and high positioning accuracy, the double-machine passive location based on time difference-frequency difference has been paid more and more attention and exploration and research. Aiming at the AWACS-UAV-TDOA joint positioning system, a positioning model is established to simulate the positioning accuracy distribution under different flight modes of AWACS / UAV. The distribution of positioning accuracy under typical scenarios is obtained, Better positioning accuracy of the flight.
