摘　　要：介绍了几种常用的温度影响频扫天线测角误差的消除方法,由于实验设备、条件的限制以及制作频扫天线等效慢波线的材料、形状有别,这些方法在工程应用中都难以采用。本文提出了一种工程上较易实现的慢波线膨胀系数测量修正法,该方法简单实用,且能满足雷达测角精度的要求。The paper introduces several means to eliminate the errors because of temperature of frequency scanning antennas. Since it's limited by qualification of the laboratory and the material, shape of the S-shaped line, the means are applied with so many difficulties. The paper illuminates a convenient practical way that modifies the heat expand coefficient of the S-shaped line. The way is simple and applicable. It meets the requirements of the precision of antenna angle measurement.
