摘要
干涉合成孔径辐射计是一种被动成像手段,可以根据目标和背景的亮温差别,实现目标探测功能,在揭露伪装、发现隐蔽目标方面有应用价值。介绍了干涉综合孔径辐射计成像基本原理,给出了一种毫米波干涉综合孔径成像系统的系统结构,分析了通道间相位误差对其性能的影响,设计了消除相位误差的校准方案,并对校准方案进行了仿真分析。
Interference synthesis aperture radiometer,which is a passive imaging measure,can detect a target based on the difference of the temperatures of the target and the background,and is suitable for unmasking and detecting concealed targets.The paper introduces the basic principle of interference synthesis aperture radiometer imaging,then presents the structure of a millimeter wave interference synthesis aperture radiometer imaging system,and analyzes the influence on the performance of the system due to the phase error of channels.Finally,the paper designs a calibration system and analyzes it by simulation.
