Radar Remote Sensing Data APPLICATIONS

Radar remote sensing  creating high resolution images of the earth's surface. These images represent the backscattered microwave energy, the characteristics of which depend on the properties of the surface, such as its slope, roughness, humidity, textural inhomogeneities and dielectric constant. These dependencies allow radar imagery to be used in conjunction with models of the scattering mechanism to measure various characteristics of the earth's surface, such as topography. Radar has become a valuable remote sensing tool for both military and civilian users. Military radar applications include intelligence gathering, battlefield reconnaissance and weapons guidance. Civilian applications include topographic mapping, geology and mining, oil spill monitoring, sea ice monitoring, oceanography, agricultural classification and assessment, land use monitoring and planetary or celestial investigations.

GEOPRECISION TECH RADAR REMOTE SENSING

RADAR stands for "RAdio Detection And Ranging". Radar is active remote sensing, it sending out pulses of microwave electromagnetic radiation. It measures the time between pulses and their reflected components to determine distance. Different pulse intervals, different wavelengths, different geometry and polarizations can be combined to roughness characteristics of the earth surface.

In electromagnetic radiation, microwave portions of the spectrum are often referenced according to both wavelength and frequency. The microwave region of the spectrum is quite large, relative to the visible and infrared, and there are several wavelength ranges or bands commonly used today.

X-band: used extensively on airborne systems for military reconnaissance and terrain mapping.
C-band: ERS-1 & ERS-2, and RADARSAT1 AND RADARSAT 2.
S-band: used on board the Russian ALMAZ satellite.
L-band: used onboard American SEASAT and Japanese JERS-1 satellites and NASA airborne system.
P-band: longest radar wavelengths, used on NASA experimental airborne research system.

radar data applications


Agriculture

Radar satellite imagery is an efficient method for mapping crop characteristics over large spatial areas and tracking temporal changes crop conditions. It need more than one acquisition date to gather meaningful crop information. 


Hydrology

Radar imagery is well suited for hydrological applications, in part because the radar is so sensitive to surface roughness and water and thus readily distinguish between water and land features.

Disaster management
Radar imagery has been used effectively in disaster responses such as earthquakes, tsunamis, flood, landslides forest fires, and other natural or technological disasters. The ability to capture the data in near-real time is essential for relief operations to map and monitor damage and for assessing the input on the future.

Marine surveillance

Radar imagery is very good for operational applications such as ship detection, oil spill monitoring, and wind and surface-wave field estimation.


Forestry

Radar imagery for forest application could help detecting structural differences in forest, and may improve forest-type mapping using textural analysis.

Contour Mapping

Mapping covers a broad range of activities, including the creation of Digital Elevation Models (DEM)s, and contour map.


Geology

In the geology sector, radar data can be used for both onshore and offshore exploration and mapping and to monitor and detect oil seeps which reduces the risk and cost of drilling. It is also used to derive geophysical terrain information such as surface roughness, which is useful for understanding processes such as bedrock weathering and the sorting of unconsolidated solid materials.
