User Systems Inc provides remote sensing focused research and development services to the government and private industries. The firm, already among the world's leaders in radar technology, is devoted to the development of airborne and space based remote sensor designs and the adaptation of data produced by these sensors for specific commercial and military applications. USIâs particular focus is the development of algorithms and signal processing systems for airborne and space-based radar and communication applications. Special emphasis is placed on synthetic aperture radar (SAR), radar design support and signal processing software systems. USI has extensive and unique experience in SAR image formation processing raw data for various airborne (JPL AIRSAR, NAWC P3, ERIM DCS, SRI FOPEN series, Essex MB SAR, Sky Research SkySAR) and space-based (SIR-C, RADARSAT-1/2, ERS-1/-2, PALSAR) platforms covering a range of frequencies (VHF, UHF, P-, L-, S-, C-, and X-bands) and polarizations. Much of this data processing is performed with USIâs ProSAR Pipes software package. USI capabilities extend over a broad range of SAR applications including interferometric SAR (InSAR), coherent change detection (CCD), ground moving target indication (GMTI), polarimetric target detection and precision geolocati
