The high resolution of the digital video broadcasting terrestrial (DVB‐T) signals leads to a dramatically large number observation samples in an integration time DVB‐T‐based passive radar. Hence, because computational complexity (CC), applying extensive cancellation algorithm and generalised likelihood ratio (GLR) detector seems be impractical radars. In this study, authors derive reduced GLR for radar presence clutter, interfering targets noise. proposed employs split received signal reduce CC substantially compared with methods that process whole at once. Moreover, reduction method does not lead degradation Doppler detection performance. Simulation results are also corroborated theoretical analysis.
