Sensitivity is the ability of microwave radiometer to detect the minimum temperature change and is an important index of microwave radiometer.In this paper
a method of calculating the sensitivity of each channel by means of the output of the correlator is proposed for the digital correlation full polarized microwave radiometer.The effects of quantization noise and crosstalk on sensitivity of analog channel and digital channel are analyzed.
