Image acquisition and processing in passive radiovision systems
- 20 Downloads
We consider the principles and methods of radio-thermal imaging in the millimeter wavelength band. An implemented system operating at a wavelength of 3 mm is briefly described, and its parameters are given. A method used to neutralize dynamic aberrations, which is necessary to create high-speed radiovision systems, is described. Super-resolution algorithms, which are the methods of improving the angular (space) resolution by using mathematical processing of the experimental data, are presented. The described results confirm the efficiency of the methods considered.
