A novel approach to solving the temperature stabilization problem of radiometer receivers is discussed, in which the classical temperature stabilization is replaced by a software-based compensation for any local temperature deviations observed. It is shown that a tunnel diode has to be incorporated as a square-law detector in order to validate this new approach. The resulting measurement uncertainty is calculated and an approximation of the effect of aging is given.
