【Abstract】 On the basis of theoretical study, experiments on passive microwave remote sensing used in the earthquake prediction were carried out. Loading experiments on rock samples of different properties and structures were made. It was obtained that the microwave radiation energy of rock samples changes obviously along with the change of stress state. The amplitudes of the change are different in different wave bands. The amount of variation with stress of different polarization is different. The variation of microwave radiation energy can be measured by microwave remote sensor on satellite. The obviously anomalous information of microwave radiation before rock failure was also discovered by experiments.更多还原
