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 μ

    m to about 2.30 μ

    m, said detection system measuring said radiance or reflectance in a first band having a wavelength in the range of about 2.05 μ

    m to about 2.15 μ

    m 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 μ

    m to about 2.30 μ

    m 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.
