Low Noise Temperature Measurement Methods In Radio Astronomy

摘要：

Noise temperature of the receiver and low noise amplifier are become lower and lower with the fast development of electronic technique, it has become difficult to measure the noise temperature accurate and rapid. In this paper, various methods of noise temperature measurements in radio astronomy are described. The factors that influence the measurement precision also are discussed.
