Digital television broadcast -based passive radar research and development

Nowadays passive radars are gaining ground and become more popular. Now, that the so far insurmountable technological limitations begin to disappear, beside the theoretical researches the investigation of realizations with the recently available hardware technologies are becoming more important. This paper presents a feasibility experiment of such a passive radar that uses DVB-T (Digital Video Broadcast - Terrestrial) signal to detect airplanes. In this paper the he principle operation of the passive radar systems has confirmed both with simulations and measurements.
