Processing of MIRANDA35 FMCW-SAR data using a time-domain algorithm

Results from an airborne SAR campaign in July 2013 using the FMCW SAR system MIRANDA35 developed by FHR are presented. This system offers a high flexibility regarding the possible swath-widths, flight altitudes and operating band-widths. The platform is an optionally piloted aircraft operated by the Swiss Procurement and technology Center armasuisse. The navigational data is a combined product from INS / GPS and dGPS data. The data were focused and geocoded with a Time-Domain Algorithm dedicated to the processing of FMCW SAR systems. Examples of resulting high-resolution SAR images are shown. The focusing quality is assessed using corner reflectors.
