对雷达波的时间延迟和多普勒频移的测量已经被用来确定内行星的轨道、半径和旋转矢量,并将天文单位与地球长度单位的关联精度提高了近五个数量级。
Measurements of the time delays and Doppler shifts of radar waves have been used to determine the orbits, radii, and rotation vectors of the inner planets and to improve by almost five orders of magnitude the accuracy of relating the Astronomical Unit to a terrestrial unit of length.
