A Digital Video Broadcast Terrestrial (DVB-T) based passive radar requires the development of a dedicated antenna array that performs satisfactorily over the entire DVB-T band. The array should require no mechanical adjustments to interelement spacing to correspond to the DVB-T carrier frequency used for any particular measurement. This paper describes the challenges involved in designing an antenna array with a bandwidth of 450 MHz. The design procedure is discussed and a number of simulated array configurations are demonstrated. The final configuration of the array will be shown as well as simulations of the expected performance over the desired frequency span.
