Exploring the impact of varied background on quantification of soil carbon content using microwave and millimeter wave signal reflectance

The quantification of soil carbon content is paramount to the advancement of soil carbon management practices, serving as the bedrock for the development and implementation of various carbon-negative and carbon-neutral technologies. These technologies are crucial in the battle against climate change and in enhancing soil health to boost agricultural productivity.  Therefore, we employ an innovative sensor technology comprised of a compact array, including 18 pairs of radar transmitters (TX) and receivers (RX) within a microwave radar array sensor, alongside a configuration of 20 TX and 20 RX pairs in a millimeter wave radar array sensor. For this kind of setup to work, the sensors need to be carefully tested to make sure they can capture changes in the soil's carbon content over time and space.
This dataset presents an exhaustive series of raw data aimed at evaluating the efficacy of these two sensor technologies in detecting soil carbon content. A distinctive aspect of this study is th..., Data Collection
Microwave Sensor:

Frequency and Sampling: The microwave sensor operated at a transmission frequency of 109.2 GHz, with each sample undergoing 20 iterations of data collection to mitigate random noise interference.

Antenna Configuration: The sensor configuration included 4 transmitters and 14 receivers, yielding 40 unique antenna pair combinations for comprehensive signal capture. The antenna pair combinations are in the readme file.

Signal Features: Each signal acquisition resulted in 8192 distinct signal features, facilitating detailed analysis.

Millimeter Wave Sensor:

Frequency Range and Sampling: The millimeter wave sensor’s operational frequency spanned from 62 GHz to 69 GHz, adopting an identical sampling strategy (20 times per sample) to ensure consistency in error reduction.

Resolution and Sampling Points: Across the specified frequency range, 150 sampling points were established, with a resolution bandwidth (RBW) of 100 kHz chosen to balance sweep time an..., , # Exploring the impact of varied background on quantification of soil carbon content using microwave and millimeter wave signal reflectance
