In 2019, landing in zero visibility conditions remains an unresolved, dangerous problem for commercial aircraft for both regional and transport markets. Common sensor solutions such as Infrared or LIDAR offer selective, limited obscurant penetration (i.e. rain, fog, snow, smoke). Honeywell’s active millimeter wave radar platform presents a sensor solution capable of seeing through all types of weather, while generating a meaningful, actionable image in real time. Results from recent field testing with the active mmW radar on approaches to multiple small municipal airports are presented and discussed, validating the application of this sensor to this need. While smaller airstrips challenge the performance of even high resolution radar sensors given reduced detectable features of prominence, the active millimeter wave radar produces real-beam imagery at the necessary angular resolutions and relevant approach ranges to support real time imaging of runways and a variety of prominent identifying guide-features. Recorded data is combined in an output with a synthetic 3D environment, supplementing the image with available a priori information. An integrated visual result is proffered that can feed into a heads-up display (HUD), with discussion about sensor improvements and additional image processing to perhaps eventually produce a comprehensive solution to the fixed wing, zero visibility landing problem.
