摘要:

识别或理解SAR系统观察到的场景需要更广泛的线索,超出了空间背景。这些包括但不限于:成像几何结构、成像模式、图像的傅立叶光谱的性质或偏振特征的行为。在本文中,我们提出了一个范式的变化,在数据科学的情况下,合成孔径雷达(SAR)数据的可解释性接地SAR的可解释的AI。它旨在使用基于完善模型的可解释数据转换来生成人工智能方法的输入,为训练过程提供知识反馈,并从数据中学习或改进高复杂性未知或非形式化模型。首先,我们介绍了SAR系统的物理层的表示:i)仪器和平台,ii)成像形成,iii)散射特征和对象,可以与AI模型集成进行混合建模。随后,给出了一些示例来演示如何实现SAR图像理解的混合建模。可信模型的观点和补充解释将在后面讨论。最后,我们得出结论,我们认为所提出的概念是适用于整个类的相干成像传感器和其他计算成像系统。

英文摘要:

The recognition or understanding of the scenes observed with a SAR system requires a broader range of cues, beyond the spatial context. These encompass but are not limited to: imaging geometry, imaging mode, properties of the Fourier spectrum of the images or the behavior of the polarimetric signatures. In this paper, we propose a change of paradigm for explainability in data science for the case of Synthetic Aperture Radar (SAR) data to ground the explainable AI for SAR. It aims to use explainable data transformations based on well-established models to generate inputs for AI methods, to provide knowledgeable feedback for training process, and to learn or improve high-complexity unknown or un-formalized models from the data. At first, we introduce a representation of the SAR system with physical layers: i) instrument and platform, ii) imaging formation, iii) scattering signatures and objects, that can be integrated with an AI model for hybrid modeling. Successively, some illustrative examples are presented to demonstrate how to achieve hybrid modeling for SAR image understanding. The perspective of trustworthy model and supplementary explanations are discussed later. Finally, we draw the conclusion and we deem the proposed concept has applicability to the entire class of coherent imaging sensors and other computational imaging systems.
