MULTISPECTRAL ENHANCED VISION SYSTEM AND METHOD FOR AIRCRAFT LANDING IN INCLEMENT WEATHER CONDITIONS

摘要

Apparatus for detecting airfield light emitters, the apparatus including a plurality of light detection cameras, each detecting at least one respective waveband of electromagnetic radiation within the electromagnetic spectrum, each of the light detection cameras producing a plurality of respective spectral images, and a processor coupled with the light detection cameras, thereby generating a multispectral image of the airfield light emitters from the spectral images, the multispectral image including a multi dimensional set of spectral values, wherein the processor further determines which combination the multi dimensional set of spectral values corresponds with a plurality of distinct light emission characteristics of the airfield light emitters by identifying a particular spectral signature corresponding to the multi dimensional set of spectral values, wherein the processor produces an enhanced image from those spectral values of the multi dimensional set of spectral values which correspond to the determined combination.
