Abstract

Radiometric monitoring allows us to obtain information about thermal electromagnetic radiation of objects in the chosen frequency band. Imaging of distant targets using their thermal electromagnetic radiation may be implemented with the help of bistatic radiometric systems. These systems are based upon measurement of the time difference of arrival of the radiation received by two or more antennas [1]-[3]. This approach has been developed in long wave radar astronomy to improve angular resolution of telescopes [4], [5].
