若已知时间和速度，我们就能求出距离来。与目前国外资科中给出的天线必须平行地轴的理论相比，本文的方法可以实现更高的跟踪精度。
汉译英，谢谢！！！
帮帮忙！
參考答案:Given Time(T) and Velocity(V), we can calculate Displacement(D). Compared with the theory that the polar axis should be in parallel with the earth axis，which appears in the literature published in current foreign journals, the method provided in this paper may fulfill higher target tracking accuracy.
[备注]
距离：事实上不应当使用distance,在物理学中标准术语是位移（displacement）。D=TV
