Paper Abstract
Sierra Nevada Corporation (SNC) has developed rotary and fixed wing millimeter wave radar enhanced vision systems.
The Helicopter Autonomous Landing System (HALS) is a rotary-wing enhanced vision system that enables multi-ship
landing, takeoff, and enroute flight in Degraded Visual Environments (DVE). HALS has been successfully flight tested
in a variety of scenarios, from brown-out DVE landings, to enroute flight over mountainous terrain, to wire/cable
detection during low-level flight. The Radar Enhanced Vision Systems (REVS) is a fixed-wing Enhanced Flight Vision
System (EFVS) undergoing prototype development testing. Both systems are based on a fast-scanning, threedimensional
94 GHz radar that produces real-time terrain and obstacle imagery. The radar imagery is fused with
synthetic imagery of the surrounding terrain to form a long-range, wide field-of-view display. A symbology overlay is
added to provide aircraft state information and, for HALS, approach and landing command guidance cuing. The
combination of see-through imagery and symbology provides the key information a pilot needs to perform safe flight
operations in DVE conditions. This paper discusses the HALS and REVS systems and technology, presents imagery, and
summarizes the recent flight test results.
