CSIR developing synthetic aperture radar
The Council for Scientific and Industrial Research (CSIR) is developing synthetic aperture radar (SAR) technology for aircraft, unmanned aerial vehicles (UAVs) and satellites.
The Council noted that synthetic aperture radars provide detailed radio frequency imagery of objects (manmade or natural) on the surface of the earth in all weather, day and night. Depending on the mode, these sensors can extract such information as detail topography, millimetric changes of the surface over time, or accurate locations estimates of moving objects in an area of interest.
“The CSIR has a deep technology base in airborne radar development in general, and also in SAR sensors specifically. With support from the Department of Science and Technology, the CSIR developed a facility to serve as a less costly, SAR research and development platform for the South African and regional remote sensing market. It provides the first building block for several product prototypes including UAV and spaceborne SAR. At present, UAV SAR sensors are being developed for medium-altitude, long-endurance type UAVs as the need for UAV-based systems continues to grow around the world.”
