The possibility of using solid-state noise signal sources as internal standards in a two-stop modulation radiometer is discussed. The dependence of the accuracy of radiometric measurements on the temperatures of internal noise standards is estimated. The possibility of calibrating internal solid-state noise sources against external reference objects with known noise temperatures is being investigated. Formulas for calculating the noise temperatures of internal standards based on known temperatur
