摘要
针对远距离地面目标的平面时差定位误差大的问题,将对流层散射信号的传播路径经过一定的近似之后,提出了一种基于对流层散射传播的超视距时差定位技术。仿真结果表明,与平面内的时差定位相比,目标距离越远,超视距时差定位的优势越明显。
In order to reduce location error of TDOA on the plane for the far emitter on the ground, the passive location of TDOA over-the-horizon based on troposcatter is put forward through approximation of the signal of propagation path. Compared with location of TDOA on the plane, it is shown that the farther the distance is, the smaller the location error of TDOA over-the-horizon.
