无源微波遥感用于地震预报的实验研究
|
摘要
对无源微波遥感用于地震预报在理论研究的基础上对不同岩性不同结构的岩石试件进行了加载实验，测量了岩石试件的微波辐射随载荷的变化．实验得出：岩石试件的微波辐射能量随岩石应力状态变化而显著变化；而且，不同的波段变化的幅度不同；同一波段不同极化方式的波随应力变化的变化量也不同；微波辐射能量的变化能够被卫星微波遥感探测器探测到．实验还发现，岩石试件临破裂前出现明显的微波辐射异常．
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.
