摘　　要：截断误差作为平面近场测试中几大重要误差项之一,对其的分析是十分必要的。分别从计算机仿真和实际测试的角度对截断误差对远场副瓣的影响进行了分析。此次分析方式结合天线方向图的特点,从全域角度对误差进行评估,结果更为可靠和精确,并得到了一些有用的规律和结果,为超低副瓣天线测试中误差的分析提供一定依据。It is essential to analyze truncation error,because it is one of the important errors in PNF measurement.The effect of truncation errors with far filed sidelobe was analyzed by means of computer simulation and actual measurement. The error analysis method combines the feature of antenna pattern to analyze the error in all angles. Because all the information on antenna pattern were considered, the results are more reliable and accurate. Some useful laws and results were obtained, and some proofs were supplied for the error analysis of ultra-low sidelobe antennas measurement.
