Ambiguity function sidelobes mitigation in multichannel DVB-T Passive Bistatic Radar

In this paper, a technique for an effective exploitation of multiple adjacent DVB-T channels as source of opportunity for PBR systems has been presented. The study has been firstly focused on the ambiguity function analysis in order to verify the effectiveness of the proposed pre-processing architecture both for single channel and multichannel DVB-T signal. In fact, results on real DVB-T data have proven a very good capability of reducing the AF side peaks with about 30 dB of processing gain (i.e.: SPR). The study has been also supported by preliminary measurements relative to three adjacent DVB-T channels. Experimental results in aerial scenario have been carried out and discussed.
