Abstract
A process for reducing erroneous plots when detecting targets using High Frequency surfacewave radar (HFSWR) is provided. Detection of genuine targets is thereby enhanced. A first difference in range of an apparent target is determined, based on range data, associated with the apparent target. A second difference in range of the apparent target is determined, based on Doppler data, associated with the apparent target. The first and second range differences are compared to one another over time to assess a consistency therebetween.
