SUMATRA (radar)
SUMATRA ( Synthetic Aperture Unmanned Millimeterwave Airborne Test RAdar ) is a miniaturized SAR from the Fraunhofer Institute for High Frequency Physics and Radar Technology FHR for remote monitoring. Due to its compact dimensions (25 cm × 16 cm × 12 cm, weight: approx. 2.2 kg) it can be used on UAVs . It can process data in real time and thus present the user with a preliminary picture of the scene immediately.
technology
In order to do justice to the limited space and power supply on a (tactical) UAV, a miniaturized radar system with reduced energy consumption was developed. This was achieved through the use of millimeter wave components. In the frequency range of 94 GHz in particular , high- frequency components with broadband properties, high resolution and completely autonomous operation were created in cooperation with Fraunhofer IAF . An analog video link, which is already available in many unmanned aerial vehicles, is used to transmit the radar signals. As a result, the SAR image similar to a video appears on the ground, which changes continuously depending on the flight speed.
