RTV Synthetic Aperture Radar

The Rapid Terrain Visualization (RTV) interferometric synthetic aperture radar sensor was designed and developed by Sandia National Laboratories for the Joint Precision Demonstration Project Office of the United States Army (Intelligence, Electronic Warfare & Sensors PEO). This radar provides the ability to generate highly accurate map products in real-time, including digital elevation models (DEMs), orthorectified SAR images, as well as a measure of the data quality.

RTV OIM and DEM

The DEMs can be produced according to the draft standards for DTED Level III or DTED Level IV, though RTV's accuracies exceed those standards. The system is capable of an absolute height accuracy of 1-meter LE90 (90% of the data within the map is within 3 feet of its true position), and the absolute ground position accuracy is 2-meters CE90 (90% of the data within the map are within a 6-foot radius circle in north/east of their true position).
