Development and preliminary experimental results of novel three-band multi-polarization airborne SAR system
Abstract
Compared with traditional single-channel synthetic aperture radar (SAR) system, the multi-band, multi-polarization SAR system can obtain more observation information to improve the ability of targets recognition, and becomes an important research direction. Therefore, we developed a new highly integrated airborne three-band multi-polarization SAR system, which works in low/medium/high (L/X/Ka band) frequency, and has the ability of full-polarity. Three-band phased array antennas are integrated a whole coplanar structure, and controlled by one task management unit. Each band of the system can work alone or together at the basis frequency and basis time, to obtain different frequency SAR images of the same area simultaneously. The results of flight experiments verify the function and performance of the system effectively. The design and application of this SAR system is significant for quantitative remote sensing observation and instructive for future radar system development.
