| 摘 要： | In order to improve the interpretation of the earth system microwave remote sensing, the research of microwavespectrum characteristics of the ground truth (earth objects) was carried out in laboratory. A laboratory formicrowave remote sensing of the earth objects has been constructed to improve the remote sensing level, thelaboratory consists of four parts: the measuring system of dielectric constants, the microwave emissivity meter,the microwave reflectometer and the microwave remote sensing simulation experiment in field. In this paper,the principle of measurement, the correction of near field process, the structure of instrument, the calibrationmethod and the measurement of the earth substances, including soil, water and oil, are discussed. The labora-tory may supply the condition for measuring the parameters of thc earth substance remote sensing and help tointerpret the remote sensing data.
