合成孔径技术和光的衍射理论

Synthetic aperture techniques and light diffraction theory

作为电磁波的一个波段,可见光和微波都能发生干涉和衍射。在大学物理教学中,如能将光学理论与微波的知识及雷达技术相结合,这不仅能让学生开阔视野,意识到普通物理知识的重要性,而且能在强化理论概念的同时又能了解前沿科技的一些本质内容,进而对大学物理产生浓厚的兴趣。本文主要是利用光的衍射理论解释合成孔径技术原理。

As a band of electromagnetic waves,visible light and microwave can generate interference and diffraction.In the teaching of college physics,if we combine optical theory with microwave knowledge and radar technology,it not only enables students to broaden their horizons and realize the importance of general physical knowledge,but also helps them enhance the understanding of theoretical concepts and comprehend the essential content of cutting-edge technology.And then it makes students generate a keen interest in college physics.In the paper,we use the light diffraction theory to explain the principles of synthetic aperture techniques.
