An 11 element crossed bowtie array antenna has been developed for use in Digital Video Broadcasting-Television (DVB-T) based passive radar. Simulation results of the array show a gain of 6 dB and measurements in anechoic chamber show more than 20 dB cross-polarized isolation. Co- and cross-polarized passive radar measurements of a Cessna 172 aircraft have been conducted and the results are compared to computation of bistatic radar cross section (RCS).
