Abstract
Systems and methods for harmonic analysis of soil are provided herein. Some methods include converting a first frequency of an operating signal into a second, higher frequency relative to the first frequency to create a stimulating signal, transmitting the stimulating signal into soil, and determining attenuation based on a comparison of a responsive signal and the operating signal.
Claims18
A method, comprising:
- selecting a first frequency for an operating signal;
- converting the first frequency of the operating signal into a second frequency to create a stimulating signal at the second frequency, the second frequency being a harmonic of the first frequency;
- transmitting the stimulating signal into a zone of interest in soil;
- receiving a responsive signal based on the stimulating signal;
- converting the responsive signal at the second frequency back into the first frequency to create a frequency-converted responsive signal in the first frequency;
- comparing a second count of the frequency-converted responsive signal in the first frequency to a first count of the operating signal in the first frequency, the first count and the second count being a number of waves;
- determining attenuation of the stimulating signal, the attenuation corresponding to a difference between the first count of the operating signal at the first frequency and the second count of the frequency-converted response signal at the first frequency;
- approximating constituent components of the soil in the zone of interest based on the determined attenuation;
- and
- increasing or decreasing a flow of water applied to the zone of interest in the soil based on the approximated constituent components.

A device, comprising:
- a harmonic sensor circuit that produces an operating signal at a first frequency and emits a stimulating signal at a second frequency that is a harmonic of the first frequency;
- a processor;
- and
- a memory for storing instructions, the processor executing the instructions to:
- control the harmonic sensor circuit to emit the stimulating signal into a zone of interest in soil;
- and
- determine attenuation of the stimulating signal in the soil based on an analysis of a responsive signal that has been converted in frequency back from the second frequency into the first frequency relative to the operating signal;
- wherein the processor determines attenuation of the responsive signal by:
- converting the responsive signal from the second frequency to the first frequency;
- comparing a second count of the frequency-converted responsive signal in the first frequency to a first count of the operating signal in the first frequency, the first count and the second count being a number of waves, the attenuation corresponding to a difference between the first count and the second count;
- and
- approximating constituent components of the soil in the zone of interest based on the determined attenuation;
- and
- increasing or decreasing a flow of water applied to the zone of interest in the soil based on the approximated constituent components.

A method, comprising:
- converting a first frequency of an operating signal into a second, higher frequency relative to the first frequency to create a stimulating signal;
- transmitting the stimulating signal at the second higher frequency into a zone of interest in soil;
- and
- determining attenuation in a responsive signal based on a comparison of the responsive signal and the operating signal;
- wherein determining the attenuation in the responsive signal comprises:
- converting the responsive signal from the second, higher frequency to the first frequency;
- comparing a second count of the responsive signal in the first frequency to a first count of the operating signal in the first frequency, the first count and the second count being a number of waves, the attenuation corresponding to a difference between the first count and the second count;
- and
- approximating constituent components of the soil in the zone of interest based on the determined attenuation;
- and
- increasing or decreasing a flow of water applied to the zone of interest in the soil based on the approximated constituent components.
