Limits of Ground Clutter CLEAN Based Cancelation in Mobile PCL Radar

Abstract

The paper presents the limitations in application of CLEAN based clutter cancelation method in mobile airborne passive radar. As the ground clutter is Doppler spread due to the platform motion it is necessary to clean not only the direct signal and time shifted replicas of illuminated signals but also Doppler and time shifted copies of the reference signal originated by clutter return. The paper discuss the maximum clutter cancelation range and maximum Doppler spread.
