Engineers at ITT Electronic Systems in Van Nuys, Calif., designed a thin-tile array radar system for sense and avoid capability in the U.S. Navy's Broad Area Maritime Surveillance (BAMS) unmanned aerial vehicle (UAV), produced by Northrop Grumman Corp. The radar will be located in the nose of the UAV.
To get the proper range and aperture you need a certain size, but the UAVs are small so a thin tile array was created that is almost conformal in nature be able to fit it into the aircraft. The technology is also scalable so ITT sees it fitting in even smaller spaces, albeit with smaller range, he adds.
The ITT system is certified for the Federal Aviation Administration's (FAA's) DO-178B certification standard. Arnold says that currently the FAA does not have a set of standards for sense and avoid, but that they are working on it. The Navy is driving this particular program, he adds.
