- R&D 100 Awards
2014 R&D 100 Winner MIT Lincoln Laboratory’s Airborne Sense and Avoid (ABSAA) Radar Panel is a stepped-notch antenna array that marks a substantial advance in the fabrication of wide-bandwidth radar systems for use aboard unmanned aerial systems (UAS).
The panel provides high performance by incorporating multifunction radio-frequency integrated circuits using a commercially available, high-volume silicon germanium (SiGe) 0.13-?m foundry process. Eliminating the separate cooling assembly and integrating the transmit/receive module into the surface-mounted assembly leads to improved reliability and simpler assembly. The panel also meets the constrained size, weight and power requirements for small platforms.
Designed especially for sense-and-avoid systems for unmanned aircraft, the panel supports both aircraft and weather detection and tracking modes in a single multifunction aperture. Smaller and less costly than competing systems, ABSAA’s successful design has the potential to facilitate the adoption of UAS in a broad range of applications, such as security and disaster response efforts, communications, aerial mapping projects and land and crop surveys.
