小麦全蚀病是检疫性土传病害,近年来随着种子调运和跨区联合收割,有扩散趋势。利用遥感技术宏观、动态和实时的特点,可更好地监测其发生发展。近年发展迅速的成像光谱技术,在对目标物成像的同时可测量其波谱特性,将辐射特性与波谱特性结合为图谱特性,或称图像立方体, Total eclipse of wheat is a quarantine soil-borne disease. In recent years, with the transfer of seeds and cross-area combined harvesting, there is a tendency of spread. The use of remote sensing technology macro, dynamic and real-time features, can better monitor its occurrence and development. In recent years, the rapid development of imaging spectroscopy technology can measure the spectral characteristics of the target while imaging the radiation characteristics and spectral characteristics for the combination of spectral characteristics, or image cube,
