Abstract本文对相干扩展目标散射的近场效应进行了研究,通过计算机理想情况下由路径相关产生的干涉效应,验并澄清了扩展目标在不同入射情况下的散射干涉的物理机制,并在基础上引入了浅粗糙面散射的概念,这为准确定标遥感仪器,实现陆其遥感测量的定量化奠定了理论基础.
Other AbstractA study has been made on near-field effect of extended target scattering in ground-based active microwave remote sensing. The analysis is started from path-different-only coherent scattering case. The results show the predicted Fres-nel zone interfering phenomenon. This somewhat explains why different measurement results may occur from different plat-form altitudes. Based on this analysis, we introduced the semi-rough scattering concept to cover more general practical cases.Results of this study may be a foundation for sensors calibration and ground-based accurate measurement in case of coherent extended targets.
