Absorption and attenuation characteristic of microwave in atmosphere and delaminating algorithm

This paper gives an accurate calculation model of microwave being absorbed in atmosphere which expands the traditional approximate algorithm that ignores the change of temperature, humidity and pressure and is limited by transmission distance, simulates the absorption attenuation in atmosphere of a certain area in our country according to its weather data from actual measurements, and finally analyses the propagation characteristic of microwave changing with frequency, elevation angle and season, and briefly explains the practical significance of this research in microwave remote sensing．
