Short Summary

This paper presents an algorithm for calculating volumetric soil moisture for a UAV-based bistatic radar system, achieving an error of no more than 10% by utilizing the soil's complex dielectric constant and validating against TDR measurements.

Objective

• To develop and verify an algorithm for calculating volumetric soil moisture for a bistatic radar system controller, specifically for a system composed of two unmanned aerial vehicles for remote sensing of soil.

Study Configuration

• Spatial Scale: Not explicitly quantified, but implies local to regional scale for remote sensing applications.
• Temporal Scale: Not specified in the provided text.

Methodology and Data

• Models used: An algorithm for calculating volumetric soil moisture based on the imaginary and real parts of the complex dielectric constant of soil. It also incorporates formulas recommended by the International Telecommunication Union Radiocommunication Sector P.527-4 (06/2017) for soil conductivity.
• Data sources: Calculated data from the proposed algorithm; comparative evaluation data from a TDR 150 soil moisture meter (Technology Spectrum, Inc.) as ground truth.

Main Results

• The presented algorithm enables the calculation of volumetric soil moisture with an error of no more than 10%.
• The calculation is based on the imaginary and real parts of the complex dielectric constant of the soil below the air-surface boundary.
• The algorithm's adequacy was verified through comparative evaluation with a TDR 150 soil moisture meter.

Contributions

• Introduction of a novel algorithm for volumetric soil moisture calculation specifically designed for UAV-based bistatic radar systems.
• Demonstration of the algorithm's capability to estimate soil moisture with a quantified error margin (≤ 10%).
• Integration of complex dielectric constant principles and established ITU-R formulas for soil moisture estimation in a remote sensing context.
