Since the radiometer is proposed to detect the salinity of the sea surface，the brightness temperature TBis in general lower than 200K[2，18].We here evaluate the sensitivity of the radiometer for the integration time ofτ=100ms and TB=150K，100K and 50K.The sensitivities for three different radiometers is shown in Tab.4.It can be seen from Tab.4 that the sensitivity of the proposed radiometer is higher than the one of the other two L-band radiometers for all of the tested brightness temperatures.
