Degraded visibility—which encompasses diverse environmental conditions including severe weather, dust kicked up during takeoff and landing and poor visual contrast among different parts of terrain—often puts both the safety and effectiveness of tactical helicopter operations at risk. Current sensor systems that can provide the necessary visualization through obscurants struggle with latency and are too large, heavy and power-intensive to comply with military rotary wing operations.
DARPA’s Multifunction RF (MFRF) program seeks to overcome these challenges and enhance the survivability and combat effectiveness of helicopters facing degraded visibility. The program aims to develop multifunction sensor technology that would enable sensor packages small, light and efficient enough for installation on existing and future helicopter designs. MFRF would enable pilots to:
MFRF completed successful flight demonstrations on a UH-60L Black Hawk combat helicopter (see video above) to demonstrate the Synthetic Vision Avionics Backbone (SVAB) technology portion of the program. The SVAB technology demonstration fused millimeter-wave radar with multiple terrain databases and onboard platform navigation to create high-resolution 2-D and 3-D visualizations of local environmental conditions. Pilots referred to the visualizations in real time to distinguish terrain features (slope, roughness, landing suitability), detect objects in a landing zone, detect and avoid obstacles, and navigate in GPS-denied conditions. The software architecture of the SVAB also demonstrated plug-and-play sensor control and display.
“These successful tests take us closer to future cost-effective, ‘plug-and-play’ systems that would improve situational awareness and mission effectiveness for manned and unmanned platforms alike,” said Bruce Wallace, DARPA program manager.
