INS/GPS/SAR Integrated Navigation With Image Geocoding

Martin Espana

Abstract:	SAR systems inherently generate highly valuable navigation data at very high rates. However, this information is usually totally ignored by the platform’s ad-hoc navigation system required by SAR data processing methods. On this behalf, a scheme that takes advantage of SAR data richness in a post processed INS/GPS/SAR integrated navigation method is here proposed. The new method, not only may considerably improve the navigation accuracy, but it also allows for geo-coding of highlighted points of the scene being imaged (geo-coding that could easily be propagated to the rest of the SAR image) by using only flight data. Potential applications are geodesy and geo-location, roads and civil works, ducts and transmission lines supervision and cadastre. For ease of reading, the article summarizes the basis of SAR processing.
