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．
Passive microwave remote sensing is used in earthquake prediction. Based on the theoretical research, rock samples with different lithologies and different structures are loaded and the microwave radiation changes with the load are measured. The experimental results show that the energy of microwave radiation of rock specimen changes significantly with the stress state of rock, and the amplitude of different band changes is different. The variation of the waves with different polarization in the same band also varies with the change of stress. The energy of microwave radiation The changes can be detected by satellite microwave remote sensing detectors. Experiments also found that the rock specimen before the rupture obvious microwave radiation anomalies.
