Abstract

This paper presents a frequency modulated continuous wave (FMCW) technology-based airborne synthetic aperture radar (SAR) system. This radar system operates on an eight-channel simultaneous dual band (X- and L-bands) in fully polarimetric mode. Compared with the traditional multiband airborne SAR, this radar system features a small size and low power consumption based on the FMCW technology. The antenna subsystem can be easily mounted behind the cargo door of a small aircraft platform without any modifications to the aircraft structure. A Cessna 208 is employed to mount this radar system in a left side looking installation. A single pass flight test is carried out in China, and preliminary imaging results are acquired and classified. The merged X–L band image provides the highest classification accuracy compared with the single X- and L-bands and optical images. The experimental results indicate that the proposed FMCW SAR is a powerful tool for terrain classification, especially for rural-urban region classification.
