Title :
Adaptive FIR filtering of range sidelobes for air and spaceborne rain mapping
Author :
Lohmeier, Stephen P.
Abstract :
This paper describes an adaptive finite-impulse response (FIR) filtering technique to reduce the range sidelobes due to surface return inherent in a pulse-compression radar used for air or spaceborne rain mapping. Its sidelobe suppression performance exceeds traditional windowing methods without a reduction in range resolution.
