WebSRTOGR performs a slant range to ground range conversion on the input SAR image, without requiring an elevation image or ground control points. SRTOGR can be used instead of the FLIGHT and STG functions when an elevation model does not exist, or where ground control points are difficult to collect (such as over water). WebSlant range calculation for a given ground range is done using the following relation. (. rp= htht+ 2.0htcos ( )) rg. fThe new range lookup index is created iteratively using the relation. gr lookup (c index )= (rpro)1000/ pixelspace. After this resampling is …

WebThe image coordinates are oriented along the flight direction and ground range (figure 1). The pixel spacing is equidistant in azimuth and in ground range. Ground range coordinates are the slant range coordinates projected onto the ellipsoid of the Earth. Webproducts are situated in slant range geometry. The slant range geometry is the natural radar one and is deﬁned by the line-of-sight distance of the radar system to each reﬂecting object. The SLC product consists of focused SAR data in zero-Doppler orientation. Furthermore, for geo-referencing orbit and attitude information directly provided 4
