一、概述可见光、红外、微波为地表遥感技术中的三个“窗口”。应用微波探测地表虽晚于可见光、红外,但却居于特殊地位。微波不仅可以透过植被和土壤,而且不受黑夜、云层、雾以及雨天的限制,因此是一种全天候遥感技术。实孔径侧视机载雷达(Real Aperture—Side Looking Airborne Radar以下简称RA—SLAR)是一种主动式的微波遥感成像系统。与常规雷达不同 First, an overview of visible light, infrared, microwave surface remote sensing technology in the three “window.” Although the application of microwave to detect the Earth’s surface after the visible light, infrared, but in a special position. Microwave is not only through the vegetation and soil, but also from the night, clouds, fog and rain restrictions, it is an all-weather remote sensing technology. Real Aperture-Side Looking Airborne Radar (RA-SLAR) is an active microwave remote sensing imaging system. Different from conventional radar
