Recent Findings from Naval Postgraduate School Provides New Insights into Radar and Sonar Research (Smear signature morphology of surface targets with arbitrary motion in spotlight synthetic aperture radar imagery)

By a News Reporter-Staff News Editor at Science Letter -- New research on Radar and Sonar Research is the subject of a report. According to news originating from Monterey, California, by NewsRx editors, the research stated, "This study develops a methodology for analytically predicting the detailed smear signature morphology of surface targets with arbitrary motion in spotlight synthetic aperture radar (SAR) imagery. The radar sensor is assumed to move with constant speed and heading on a level flight path with broadside imaging geometry."

Our news journalists obtained a quote from the research from Naval Postgraduate School, "Cases of uniform target motion exhibit morphology of simply curved smear shapes, as has been reported previously. However, the present analysis shows that non-uniform target motion can cause complicated smear shapes in spotlight SAR imagery. Specifically, the method of stationary phase is applied to local subaperture SAR images to yield analytic non-parametric expressions for the morphology of smear signatures within spotlight SAR imagery for surface targets with arbitrary motion trajectories."

According to the news editors, the research concluded: "This predictive capability offers the potential of extracting some characteristics of true target motion based upon the induced SAR smear signatures alone."
