Forest Inventory

Measuring forest ground height, canopy height, forest height, diameter at breast height (DBH), volume density, and identifying the highest trees.

​

- Achieved an accuracy of 2% for forest height, DBH, and volume measurements.

Soil Moisture Measurement

Determining the gravimetric soil moisture of the upper 20 cm layer of the subsoil using radar data.

​

- Gravimetric soil moisture with a resolution of 10 meters and accuracies of 10% absolute and 5% relative gravimetric moisture.

Ant Nests Location

Detecting and mapping ant nests under the forest using radar tomography.

- The radar tomography detected ant nests with an accuracy of 20 meters for location and 20% for volume estimation.

3D tomography of underground structures

- Detected high-reflectivity volumes up to 40 meters deep, suggesting the presence of hollow cavities or regions with different soil densities.

- Identified low-reflectivity surfaces at 20 meters deep, potentially indicating high-reflectivity materials such as water tanks.
