Abstract

Synthetic aperture radar (SAR) imaging technology has continued to evolve over the last few decades and the future holds promise. Beam raster scanning for 2D flyover SAR is yet another milestone in the evolutionary path of SAR imaging. This SAR imaging technique may have application in areas like passive unmanned aerial vehicle SAR. This paper builds on the 2D aperture synthesis concepts based upon rigorous analytical results presented by the authors earlier and elucidates the characteristics of sombrero point spread function and reconstruction in comparison to sine point spread function and reconstruction. This paper also explains the concept of 2D target area data collection scheme called flyover beam raster scanning
