摘要
射电观测经常受到各种非线性现象的约束，使系统性能达不到原有要求。本文主要对总功率辐射计中的非线性影响作了分析研究，并对常见的两种非线性特性提出了改正的方法。
Radio astronomy observations frequently suffer from various nonlinearity in the receiversystem, which could not make a system performance attain predeterminate object. Mainnonlinearity in a total power radiometer receiving system is analysed and studied' And thecorrecting methods for two nonlinearties are presented.
