Active and passive remote sensing techniques have been found useful in investigating surface conditions such as ice, snow, vegetation, and soil moisture. This research effort expands this activity to the use of microwave remote sensing for characterization of geophysical media. Theoretical models that account for absorption, layering, and scattering will be developed to facilitate interpretation of active and passive remote sensing data. These models will then be used and compared to the results of controlled laboratory experiments.

主动和被动遥感技术已被发现在调查冰、雪、植被和土壤湿度等地表条件方面很有用。这项研究工作将这一活动扩展到使用微波遥感来表征地球物理介质。将开发考虑吸收、分层和散射的理论模型，以便于解释主动和被动遥感数据。然后，这些模型将被使用，并与受控实验室实验的结果进行比较。
