ICE AND SUPERCOOLED WATER DETECTION SYSTEM |
摘要 |
A system for detecting ice or supercooled large droplets within an area of interest having a detection system measuring radiance or reflectance of the area of interest when exposed to shortwave infrared radiation having a wavelength in the range of about 2.05 μm to about 2.30 μm. The detection system measures the radiance or reflectance in a first band having a wavelength in the range of about 2.05 μm to about 2.15 μm and outputting a first band signal, and further measures the radiance or reflectance in a second band having a wavelength in the range of about 2.15 μm to about 2.30 μm and outputting a second band signal. A processing unit determines a ratio of the first band signal and the second band signal and compares the ratio to a predetermined critical ratio and outputs a determination signal indicating presence of ice or supercooled water droplets. |

1. A system for detecting ice and/or water within an area of interest, said system comprising:
a detection system measuring radiance or reflectance of the area of interest when exposed to shortwave infrared (SWIR) radiation having a wavelength in the range of about 2.05 μm to about 2.30 μm, said detection system measuring said radiance or reflectance in a first band having a wavelength in the range of about 2.05 μm to about 2.15 μm and outputting a first band signal, said detection system measuring radiance or reflectance in a second band having a wavelength in the range of about 2.15 μm to about 2.30 μm and outputting a second band signal; and a processing unit determining a ratio of said first band signal and said second band signal, said processing unit comparing said ratio to predetermined critical ratio ranges and outputting a determination signal indicating at least one of presence of ice when said ratio is within a first range of said predetermined critical ratio ranges and presence of water when said ratio is within a second range of said predetermined critical ratio ranges. |
