What limits the effectiveness of time domain gating?
Answer: A
Resolution in time is inversely proportional to the swept bandwidth, so a reflection whose extra path length is short compared with that resolution overlaps the direct arrival and cannot be gated out. Reflections from close structures are therefore the hardest to remove. The transform is routine, gating does distort the band edges but not by removing low frequencies as such, and antenna size is not a restriction. A resolution limit set by bandwidth appears wherever time and frequency are exchanged.
