基于对带罩天线的辐射方向图数据进行处理，提出了一种改进的天线罩瞄准线误差计算方法。该方法以单脉冲天线差方向图在电轴附近的对称性为理论基础，借助等电平平均法计算天线辐射方向图的零值位置，获取天线罩瞄准线误差，降低了测试场地对天线方向图的影响，有效提高了天线罩瞄准线误差的测试准确度。

Based on the processing of the radiation pattern data from antenna with a ra- dome, an improved calculation method of radome aiming error is presented. According to the symmetry of monopulse antenna difference pattern near the electrical axis, the electrical null position of the antenna pattern is calculated by the method of the average of equal-level posi- tions, and the radome aiming error is acquired. By this method, the influence of the antenna pattern caused by the test place is reduced and the test accuracy of radome aiming error is ef- fectively improved.
