The sense and avoid (SAA) capability is a key issue in the integration of Unmanned Aircraft Systems (UAS) into the common airspace. Besides the lack of a regulatory framework in most countries, some technological challenges are still not resolved which holds back routine UAS applications. Most UAS or Remotely Piloted Aircraft Systems (RPAS) have no SAA capability. The separation for these aircrafts must be done solely by the Air Traffic Control (ATC) which is not cost effective. Furthermore, in the case of a lost link, there should be some kind of collision avoidance capability onboard; otherwise, if we want to maintain the current safety level of the air traffic system, a single unmanned airplane would block a significant sector of the airspace. Besides the safety and cost issues in the RPAS case, general aviation could benefit from a solid SAA system as well. An SAA instrument could support pilots in the case of conflicting instructions coming from the different layers of collision avoidance (for example ATC and onboard devices) and in some cases it could extend the range for the non-cooperative collision avoidance done by the pilots. An ideal SAA system would be cost effective, lightweight, and low-power in order to minimize the negative effect on cost, make application onboard small unmanned aerial vehicles (UAVs) possible, and maximize flight time of the aircraft.
