Abstract

This paper presents investigation results on detection performance of passive radar systems using DVB-T (Digital Video Broadcasting – Terrestrial) illuminators of opportunity with the SW5 stationary target model and statistically independent additive clutter model with different distributions. The investigation was performed by simulations on MatLab software, including the generating process of DVB-T signal and clutter with given distributions, cross-correlation processing, CFAR (Constant false alarm rate) detection, with a large number of trials to derive the detection probability curves as a function of signal/clutter ratio at the cross-correlation processor's entrance.
