High range resolution multichannel DVB-T passive radar: Aerial target detection

A method for improving the range resolution in passive radar systems is to jointly use more than one transmission channel of the same Illuminator of Opportunity (IO). This paper specifically focuses on the exploitation of three adjacent Digital Video Broadcasting - Terrestrial (DVB-T) channels for achieving high range resolution profiles with a passive radar system operating in air surveillance scenarios. Firstly, an analysis of the ambiguity function obtained from a multichannel DVB-T source is presented. Afterwards, the experimental scenario is defined and a preliminary detection result on aerial targets is shown.
