【摘要】 在研究了混合像元热辐射方向性规律的基础上 ,以连续植被冠层为例 ,提出了利用热红外多角度遥感数据 ,直接反演混合像元组分温度的方法。与多通道数据相比 ,多角度信息间的相关性要低得多 ,它主要取决于植被冠层的叶倾角分布函数 (LAD)。因此更容易达到反演精度小于1K的目的。更多还原

【Abstract】 A new method was offered to retrieve component temperature of mixed pixel with multi\|angle thermal infrared data based on the law of directionality of thermal radiance of mixed pixel.To take continuous vegetation canopy as an example,the correlation coefficients among multi\|angle thermal infrared data are less than their counterpart of multi\|channel which mainly depend on the distribution function of leaf angle(LAD),therefore,it is easier to keep accuracy of retrieved component temperature within 1?K than its counterpart.更多还原
