Microwave remote sensing of soil cover

For the purpose of remote sensing in microwave the experimental studies on dielectric properties of wet soils and grounds in microwave and effect of bound water on their dielectric properties are conducted. The applicability of empirical refractive model for description of complex dielectric constant of soils containing bound water is examined for temperatures above and below 0 degreesC. A possibility to detect the point of transition from bound water predominance to free water is demonstrated. The principle of creation a database on dielectric properties of soils with the aim of interpretation remote radiometric measurements is proposed. Some results of field researchers on the test sites of Altai region are considered.
