Range-time sidelobe characterization of the ELDORA radar
All radars that employ pulse compression techniques suffer from range-time sidelobes to some extent; the dual beam scanning airborne ELDORA radar is no exception. The effects of range-time sidelobes are readily apparent in the ground return data which appear several range gates wide. This greatly limits the radar's ability to accurately measure near surface winds. This paper reviews the cause of range-time sidelobes in general and more specifically how they occur in ELDORA. A recent technique for reducing range-time sidelobes in ELDORA is discussed and supporting data from the IHOP-2002 research project is shown. In addition, a future plan for their complete mitigation is proposed.
