An Image Regulation Technique for Passive Millimeter Wave Focal Plane Array Imaging Radar System

Passive millimeter wave imaging radar systems provide advantages over the optical and infra-red (IR) systems, especially under the poor weather with fog, clouds and light drizzle which are effectively transparent at millimeter wavelength. Due to the higher diffraction in millimeter wave range, the images are often acquired with poor resolution. In order to enhance these images and recover the spatial resolution, super resolution algorithms are often applied. In this paper, we presented and calculated the ideal imaging process of millimeter wave focal plane array imaging radar systems and developed an image regulation technique. Examples of applying our technique will be given and the results seem to be promising
