摘    要:根据微波辐射原理特性,研制了一种双通道狄克辐射计用于进行污秽检测。该辐射计利用水平、垂直两种极化方式对污秽物进行测量。通过实验研究获得大量数据,分析了两种极化方式下等值盐密、等值灰密随天线温度的变化关系。结果表明,污秽绝缘子的等值盐密、灰密与天线温度是幂函数关系。通过拟合技术得到经验公式,并对实验测量值与拟合公式进行误差分析。该研究进一步验证了利用微波辐射计检测绝缘子污秽是切实可行的。

关 键 词:绝缘子污秽  辐射计  检测

Abstract:According to the characteristics of microwave radiation,a new dual-channel Dicke radiometer has been developed. It can be used to detect insulator contamination by the polarizations in horizontal and vertical directions. With a large number of data obtained by experiments,the relationship between equivalent salt deposit density (ES-DD)/non-soluble deposit density (NSDD)and the antenna temperature was researched. The results showed that the insulator ESDD/ NSDD with the antenna temperature is a power function. Calculation formula is obtained by data fitting,and the error was analyzed. This study provides a new method of detecting insulator contamination by microwave radiometer.
Keywords:ESDD  NSDD  insulator contamination  radiometer  detection  ESDD  NSDD
