Sense and avoid sensor for UAVs makes progress
Sierra Nevada Corporation (SNC) has conducted the second airborne demonstration of its prototype radar Airborne Sense and Avoid (ABSAA) sensor for UAVs.
The company reported that the demonstration saw the sensor repeatedly detect and track airborne intruders resulting in over 60 seconds of avoidance time, exceeding current requirements.
The sensor is being developed as part of the US Air Force Research Lab’s Multi Sensor Detect Sense and Avoid (MSDSA) programme. This programme aims to advance sense and avoid technology for UAVs at a lower cost than electronically steered antennas.
Greg Cox, corporate vice president of Communication, Navigation, Surveillance/Air Traffic Management, SNC, said: ‘Our sense and avoid sensor incorporates SNC’s unique Electronically Reconfigurable Array (ERA). The entire sensor has been designed and developed as an ABSAA building block that is easily scalable to serve as the solution to multiple UAV CONOPS and installation challenges.’
