An important step between image formation and classification is to determine which of the ISAR images generated by the sensor really provides the most useful information for classification. This paper proposes multiple quality measures (QM) to automatically select ISAR images that carry good classification information. These features are used to also investigate the effect of dwell-time on ISAR imagery. Measured data of maritime vessels are used to evaluate the quality measures and to determine the minimum dwell-time for ISAR image formation.enInverse synthetic aperture radarISARDwelltimeQuality measureImage contrastImage entropySignal-to-noise ratioSNRMaritime vesselsConference PresentationSteyn, J., & Nel, W.
