我们提出了一个物理模型，描述了一个粗糙的异质表面的红外传感器获得的辐射。该模型预测在城市地区等复杂景观上看到的辐射，并提供对信号的准确分析，因为每个组件都可在地面和传感器级别获得。此外，它还允许对不同仪器的数据进行比较。两个代表性的情况下（自然和城市）进行了分析，以显示传感器信号的组成和结构，并强调具有3D模型的重要性，特别是对于崎岖的表面，其中环境权重在整个频谱域。
We present a physical model describing the radiance acquired by an infrared sensor over a rugged heterogeneous surface. This model predicts the radiance seen over complex landscapes like urban areas and provides an accurate analysis of the signal, as each component is available at ground and sensor level. Plus, it allows data comparison from different instruments. Two representative cases (natural and urban) are analysed to show the composition and the construction of the sensor signal and to highlight the importance of having a 3D model, especially for rugged surfaces where environment weights in the overall spectral domain.
