The exploitation of multiple DVB-T channels for a passive radar system has been considered to enhance the radar range resolution. A preliminary study has focused on the AF analysis to verify the suitability of a multichannel DVB-T signal for radar applications. The theoretical study has been supported by preliminary measurements relative to three adjacent DVB-T channels. Experimental results in an aerial scenario through the use of SDR hardware have been carried out and showed a clear improvement in range resolution when using multichannel rather than single channel DVB-T signals. It may be proven in the near future that target classification of noncooperative target radar imaging will be enabled by a high resolution DVB-T passive radar that is obtained by exploiting multichannel DVB-T signals.
