Modularity Design of Active Phased Array Antenna for Large Aperture Spaceborne SAR
摘要
Abstract
A large-aperture spaceborne Synthetic Aperture Radar(SAR)active phased array antenna is designed in a modular approach.The antenna array is divided into modules,and the radio-frequency network,control network,power supply network and the structure are respectively designed in a modular approach.The designed effective aperture of the antenna is approximately 176λ0×31.5λ0,and a total of 11 antenna modules are partitioned.This antenna operates in the X-band and has the advantages of high gain,wide instantaneous bandwidth,and two-dimensional electrical scanning.It has successfully completed in-orbit environmental adaptability tests,demonstrating that the proposed modular design method is highly suitable for the design requirements of large-aperture spaceborne SAR active phased array antennas.关键词
