多角度航空遥感飞行试验是黑河试验的重要组成部分,在介绍了机载红外广角双模式成像仪(Wide-angle Infrared Dual-mode line/area Array Scanner,WiDAS)的研制背景、硬件构架和多角度成像原理之后,结合其数据特点,详细描述了WiDAS数据处理流程并设计了WiDAS系统的红外产品体系。最后,用地面同步测量数据对定标后的WiDAS辐射亮温进行了验证,并从飞行数据中提取了黑河试验区6种典型地物的辐射亮温随观测角度的变化情况。

  Wide-angle infrared Dual-mode line/area Array Scanner (WiDAS) is an airborne remote sensing instrument designed to acquire multi-angle infrared remote sensing data, which is one of the essential observation in the simultaneous remote sensing and ground-based experiment in the Heihe river basin. After a brief introduction of the research background and hardware structure, the processing algorithms and product system for WiDAS thermal data are subsequently proposed according to the characteristics of WiDAS imaging system. In the end, the radiant directionality of six typical ground objects is extracted from calibrated and georectified WiDAS data, which indicates WiDAS as a good data source for study of land surface radiant directionality in MIR and TIR band.

Key words: Multi-angle remote sensing    Radiant directionality    Radiometric calibration    Geometric calibration
