Compact, low cost, airborne SAR interferometry for environmental monitoring

First results of repeat pass SAR Interferometry (InSAR) from Selex ES´s compact, experimental airborne synthetic aperture radar (SAR) system are described for civilian environmental monitoring. The system is a low cost, lightweight (<;10kg), X-band, Active Electronically Scanned Array (AESA) SAR platform, which provides greater opportunities of access to InSAR data as it can be placed on helicopters, fixed wing aircrafts and UAVs. Results of high resolution (<; 2m) digital elevation models (DEMs) produced are shown for two sites of environmental interest. The first DEMs produced compare well to those from other datasets.
