  • Publication number: 20250076218
    Abstract: A method for determining soil moisture of a scene includes (i) generating a first antenna output in response to an upwelling thermal emission from the scene, (ii) generating a second antenna output in response to a downwelling thermal emission from sky above the scene, (iii) coupling the first antenna output and the second antenna output to yield a combined output having a quadrature phase difference between the first antenna output and the second antenna output, (iv) calculating a brightness-temperature difference based at least partially on the combined output, and (v) calculating a soil moisture based on soil-vegetation radiative transfer model using the brightness-temperature difference.
    Type: Application
