Abstract
Infrared signatures of aircraft are the basis for detection and
monitoring. In past years, most of the studies focused on the aircraft’s
infrared signature in the mid-wave spectral region and long-wave spectral
region for missile guidance or aircraft survivability studies. For the
security of civil aviation, methods and instruments that can detect and
monitor aircrafts from space are expected to be developed in the coming
years. A short-wave infrared hyperspectral imager aboard the Tiangong-1
spacecraft acquired some civil aircraft’s spectral data. The differences
between the aircraft and the background in their spectral signatures are
analyzed and discussed. Less absorption in the vapor absorption bands and
a reflection spike is discovered at the 1.84 μm spectral band. The result
shows that 1.84 μm and other vapor absorption bands can make contributions
to aircraft detection in the daytime.
