SUSTAINABILITY IS EFFICIENCY
TerraRad is working to create synergies between societies and our planet’s finite natural resources. We aim to optimize efficiency and sustainability by harnessing the potential of remote sensing technology. Putting the interest of the natural world at the forefront of our own development, our novel technology presents opportunities in precision agriculture, wildfire, aerospace, and cold region research applications.
WHAT WE DO…
At TerraRad Tech, we produce and market a unique electromagnetic remote sensing device known as a microwave radiometer. Our products include the sensor hardware and affiliated software packages. We offer both UAV- (multi-rotor-drone-) based, and ground-based systems. Applications for our sensor include: field mapping in precision agriculture, satellite validation for earth observation in the aerospace sector, active wildfire mapping, ice & snow (cryosphere) monitoring, hydrology and risk assessment.
OUR MAJOR APPLICATIONS INCLUDE:
BACKGROUND ON OUR TECHNOLOGY…
Microwave radiometry is the premier remote sensing technology for soil moisture. Consequently, the European Space Agency SMOS and the NASA SMAP satellites use this technology to monitor global hydrology and soil moisture for weather prediction. Our patented technology can map, from a drone, 5-10 cm depth soil moisture, through crops, with less than 2% error. This provides high resolution maps, enabling practical use cases for agriculture. The system is capable of simultaneously mapping vegetation water content, without saturation observed in other vegetation indices derived from visible and infrared sensors. Our microwave radiometer operates in the 21 cm wavelength (“L-band”) regime of the electromagnetic spectrum.
WHY USE A DRONE-BASED MICROWAVE RADIOMETER?
Satellite-based radiometers lack the ground resolution to view farm-scale data, while radars are hindered by vegetation. Other satellite derived vegetation indices (such as NDVI and Leaf Area Index) do not have the ability to see through crops. Drone-based multi- and hyper-spectral sensors can monitor the top layer of crops, but have no sub-surface measuring capability. TerraRad Tech offers a more proactive approach to crop health as opposed to these reactive methods widely used in the market today. Buried soil moisture probes, also used in agriculture, lack the ability to quantify spatial variability.
