Ground clutter suppression: Preliminary analysis of Qujing incoherent scatter radar
Incoherent scatter radar (ISR) detects the Thomson scatter echo of free electrons to inverse ionosphere parameters and is thought as the most powerful instrument to observe the ionosphere on the ground. In fact there are usually severe ground clutters around altitude 100km in the echo data. This paper introduces pulse subtraction to deal with ground clutter by using the Qujing incoherent scatter radar data. The results show that this pulse subtraction suppresses ground clutter well.
