Antenna structural design based on phase center error analysis of airborne ATI-SAR
摘要
Abstract
Along-track interferometric synthetic aperture radar (ATI-SAR) detects ground moving objects and measures their velocities.Phase center error is a major error source of ATI-SAR.Not only does the constant offset need external calibration,but also the rigidity of antennas should prohibit the drifting errors.We analyzed the drifting errors caused by antenna's mechanical deformation and proposed requirements for structural design of antenna to meet the velocity measuring requirements,providing theoretical foundation for airborne ATI-SAR antenna structure design.关键词
