The project deals with the research and development (RaD) of a radiolocation mapping and navigation system and with the extension of knowing-how in this field in the Czech Republic. The system consists of a radiolocation unit based on SAR (Synthetic Airborne Radar) technology, an inertial navigation unit, and of a control module. The integration of mentioned units brings a unique system fulfilling functions of a continual navigation and the evaluation of landscape image even under adverse weather conditions.
