  • Soil humidity microwave remote sensing device with multi-mode compatibility via GNSS-R and a method of using the same
    Patent number: 11828715
    Abstract: The disclosure relates to the technical field of soil humidity measurement, in particular to a soil humidity microwave remote sensing device with multi-mode compatibility via GNSS-R and a method of using the same. The device includes a direct RHCP antenna, reflective RHCP antenna, a reflective LHCP antenna, a combiner, switches, preamplifiers, down-conversion modules, sampling and quantizing modules, a capturing and closed-loop tracking module, an open-loop tracking module, a position calculating and controlling module and a soil humidity inverting module. The soil humidity microwave remote sensing device with multi-mode compatibility via GNSS-R realizes flexibly switching among different GNSS-R soil humidity microwave remote sensing working modes, so that the soil remote sensing device can fully utilize advantages of the different working modes to realize compatible multi-mode observation.
