Frequency-Domain Filtering Fails on Simulated Multipath Ghosting in Aerial Imagery

Frequency-domain filtering of simulated multipath ghosting in aerial imagery. A negative-results study showing why frequency-domain notch filtering fails on this interference, evaluated on image quality and downstream detection.

Constraint

Multipath ghosting degrades aerial imagery and downstream detection.

Built

Simulated interference with frequency-domain notch filtering on image quality metrics.

Happened

Filtering fails on this interference; documented as a negative result for IECON.
