Paper Abstract

In this paper we present the overview of problems and difficulties, which are common in passive millimeter-wave imaging or radiovision. The central part of the article is dedicated to mathematical resolution enhancement methods - superresolution. We consider several algorithms and discuss benefits and drawbacks they have. Performance of the algorithms is demonstrated using a set of test images, both simulated and real-life. Such advanced questions as subpixeling technique and artifact suppression using the wavelet transform are also reflected in the paper. The illustrations are included in order to demonstrate significant improvement of the resolution along with artifact suppression achieved on real-life observed images. Influence of side lobes of PSF on image quality is considered.
