SAR RADAR

Synthetic aperture radar (SAR) is radar mapping

technique for generating high-resolution maps in

slant and cross range. It is possible because the

SAR radar is installed on moving platforms. The

moving radar can be treated as a long linear

antenna array with a large amount of dipoles,

which length is equal to radar flight path. The

very long antenna has very narrow beamwidth

and can ensure the very high cross-range

resolution. It means that synthetic antenna

beamwidth is much more narrow than real
