Abstract
An electromagnetic wave imaging system and a method of correcting an antenna array signal are disclosed. In an example, the electromagnetic wave imaging system may include an antenna array, configured to receive electromagnetic wave from a target object and convert the electromagnetic wave into an electrical signal; a signal processing unit, configured to process the electrical signal to obtain an image of the target object; and a distance measuring device, configured to measure a distance of the target object from the antenna array, wherein the signal processing unit corrects the electrical signal based at least in part on the measured distance.
