摘要

The excess noise ratio (ENR) of a noise source is largely dependent on the ambient temperature variation. In this paper, we discuss a method to compensate for the ENR of a noise source with respect to ambient temperature variations. From the measured quantities of the receiver and noise source from the setup, calibration coefficients of the noise source are extracted according to the relationship ...
