WHAT IS AIRBORNE HYPERSPECTRAL REMOTE SENSING?
All of the various
components of the earth's surface reflect and absorb energy in both
the visible and non-visible portions of the electro-magnetic spectrum.
Each distinct compound such as a mineral, plant or man-made material
has a unique composition which can be identified by its unique spectral
signature. Hyperspectral sensors can detect and differentiate a
wide variety of compounds well beyond the capabilities of the human
eye or other visual imaging devices. NARROW SWATH (PROFILING) HYPERSPECTRAL SYSTEM Ekwan-X has developed, tested, and put into use a narrow swath (profiling) hyperspectral system (Ekwan-X-1). Ekwan-X-1 is designed to be flown at low altitude on the same airborne platform with geophysical equipment (magnetometer, radiometrics, etc.). This allows the simultaneous acquisition of airborne hyperspectral and geophysical data. The Ekwan-X-1 narrow swath (profiling) hyperspectral system consists of two down looking hyperspectral profiling sensors and one upward looking downwelling irradiance sensor. Each sensor records 366 contiguous spectral channels covering the 350 nm to 2500 nm wavelength range. The sensor simultaneously collects two parallel lines of contiguous pixels and downwelling irradiance data. The system is light weight and is easily installed on a variety of aircraft. Through Ekwan-X’s technology development program, Ekwan-X has alliances with some of the world's most sophisticated space and airborne imaging corporations. Ekwan-X has also available the use of the most advanced airborne hyperspectral imagers. This imager
has 384 contiginous spectral channels covering the 400 nm to 2500
nm wavelength range with a ground resolution capability between
0.8 m and 7 m and swath widths up to 2 km depending on altitude.
With this instrument Ekwan-X has the most advanced hyperspectral
imagery available in the world today. The application of airborne hyperspectral remote sensing for the assessment and analysis of the earth's surface for mineral exploration provides Ekwan-X with a significant competitive advantage. |
Airborne
hyperspectral remote sensing has been described as "airborne
geo-chemistry" for its ability to differentiate a wide variety
of materials that comprise the surface of the earth.
