A radiothermomet er for surface temperature measurement is designed with an enclosed chamber to eliminate any uncontrolled circumferential irradiation. This paper addresses the signal -to -noise ratio (SNR) and the noise -equivalent temperature difference (NETD) equations in terms of system parameters. SNR of an enclosed radiothermometer In an infrared system, a detector's performance is usually characterized by the parameter
