Detection &
Ranging)
imaging methods
Multispectral and
Hyperspectral
Imaging
Polarimetry
Imaging
Synthetic Aperture
Radar (SAR)
POLARIMETRY IMAGING
Measures degree of polarization of light.
Method used by ELTE - Partner institution.
Generally used in agriculture, defense, etc.
MULTISPECTRAL & HYPERSPECTRAL IMAGING
collects a few image layers of the same scene, each of them acquired at
a particular wavelength band.
captures ultra-fine spectral details across hundreds of narrow
wavebands, enabling intricate material analysis and target detection.
Main difference between
Multispectral imaging and
Hyperspectral imaging is
that hyperspectral image
contains more than 100
bands, while multispectral
images have fewer.

5. LIDAR (LIGHT DETECTION & RANGING)
determine how far objects are away from each other by
shining a laser onto a target and analyzing the light that
bounces back.
Two types of LiDAR: topographic and bathymetric.
provides accurate topographical data and can penetrate
forest canopy, which polarimetric sensors may struggle
with.
SYNTHETIC APERTURE RADAR (SAR)
create detailed images of the Earth's surface regardless of time of day or weather conditions. 
type of active data collection where an instrument sends out a pulse of energy and then records the amount of that energy reflected back
after it interacts with earth. 
Polarization and Scattering Mechanisms.
Radar can collect signals in different polarizations by
controlling the analyzed polarization in both the
transmit and receive paths.  While the orientation
can occur at any angle, SAR sensors typically
transmit linearly polarized. The horizontal
polarization is indicated by the letter H, and the
vertical polarization is indicated by the letter V.
