Method Adaptive canceling methods were used to reduce the noise of temperature signal gained, and enhance signal to noiseratio.
方法采用自适应抵消技术最大限度地降低所读取温度信息的噪声干扰，提高信噪比。

The system provides two major functions including measuring noisetemperature of low noise devices and calibrating the Excess noise Ratio (ENR) of solid-state noise sources.
该系统主要完成两大类功能：测试低噪声器件的噪声温度和校准固态噪声源的超噪比。
