| Abstract: | 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. |
