Echodyne Corp. announced the development of MESA-DAA, an Airborne Detect and Avoid (DAA) radar for small to medium-sized unmanned aircraft systems (UAS). The small, lightweight, and low power DAA radar will operate at K-band and be capable of rapidly scanning a broad field of view in azimuth and elevation at ranges out to 3km. MESA-DAA is based on Echodyne’s patented Metamaterials Electronically Scanning Array (MESA™), which offers breakthrough cost, size, weight, and power (C-SWAP) improvements over traditional electronically scanning array technology.
