Abstract:
|
Soil moisture and land surface’s temperature are
proxys of forest fires risk. In the frame of the DANTE project,
ADTelecom (Barcelona, Spain) is working in the design of an
instrument: 1) to estimate the risk of forest fires, based on
surface temperature and soil moisture measurements, 2) to detect
and localize the ignition of forest fires by image processing
techniques, and finally, once the forest fire has ignited, 3) to
estimate the direction of propagation of the fire based on short-
range wind lidars. This paper is focused on the design of the soil
moisture remote sensor. To do that, some of the existing
techniques for ground-based soil moisture monitoring based on
the use of signals of opportunity transmitted from Global
Navigation Satellite Systems after reflection on the land surface
are first reviewed. Then, some conclusions drawn to design a new
and simpler remote sensing instrument for soil moisture
monitoring taking the advantages of all each of the individual
systems revised before. Finally, the instrument developed is
presented together with some preliminary results, pending on the
development of more refined retrieval methods through the
processing of more experimental data. |
