从理论上研究了无线电波在一颗行星的边缘处衍射和在大气层中折射的特性。从地球上看，一个飞掠火星的航天器的轨迹涉及到航天器被行星掩星，对其与火星之间的通信链路的大气扰动进行了示例计算。结论是，这样的无线电掩星实验可以提供关于行星大气尺度高度和表面密度的重要新信息，并且当与其他信息相结合时，可以帮助确定大气成分。
Theoretical studies have been made of the characteristics of radio waves diffracted at the limb and refracted in the atmosphere of a planet. Sample computations have been made of atmospheric perturbations to the communication links to and from a Mars flyby spacecraft having a trajectory that involves occultation of the spacecraft by the planet as seen from the earth. It is concluded that such a radio occultation experiment can provide important new information on the atmospheric scale height and surface density of a planetary atmosphere, and, when combined with other information, can help determine atmospheric constituents.
