Bistatic backscatter
WebThis work presents non-coherent frequency shift keying (FSK) for bistatic backscatter radio; FSK is appropriate for the power limited regime and also allows many RF tags/sensors to convey information to a central reader simultaneously with simple frequency division multiplexing (FDM). For applications that require large numbers of wireless … WebCalculation of attenuation, backscatter and brightness temperature are then made using these models. A connection between brightness temperature and the backscattering cross section can then be made to the soil moisture for inversion purposes. ...
