Remote sensing using radar technologies is a constantly evolving field of work. The possibilities offered by radar devices are still to be explored. Their applications have place in fields as diverse as the meteorology, the security, the characterization of foods, of soils and a long etcetera. This is one of the most important areas in atlanTTic, the patents achieved in this area is proof of the quality of the results obtained.
In the last two decades, meteorological agencies in developed countries have implemented Doppler radar networks for the detection and monitoring of meteorological phenomena. These radars are able to locate precipitation, measure trajectories and estimate the type of rainfall and quantity. Within the meteo radar exists a type called polarimetric radars. These have the capacity to emit waves with different polarization, allowing to introduce more information to contrast data. The success and benefits (early warning of storms and tornados, prediction of floods, control of hydrographic resources, etc.) derived from the operation of these radar networks have led to the expansion and continuous updating of the same.
In other respects such as security in public places, the growing threat of terrorism, surveillance of people at security checkpoints such as airports and bus and train stations is increasingly important. Millimeter wave systems, generally in the 30 to 300 GHz band, are the most promising solutions because millimeter waves are non-ionizing and therefore pose no known health hazards at moderate power levels. Millimeter wave scanners allow to offer a solution to this technological demand, due to its good compromise between resolution of the obtained image, ability to penetrate through tissues and other materials, use of non-ionizing radiation, and relatively low cost.
