摘　　要：紧缩场电气测试调整是保证紧缩场最终电气性能指标的一个重要过程。在此过程中,需要根据电气性能检测结果对紧缩场电气设计和机械设计进行必要的调整,排除或尽量控制影响静区的干扰波。在满足近轴近似的条件下,通过平面波角谱分析的方法可以准确地预测干扰波的入射方向和大小。对入射方向相同或相近的两列干扰波,可以采用时域分析方法进行辅助分析。The electrical testing readjustment is an important procedure to ensure compact antenna test range (CATR) performance. In this process, necessary electrical and mechanical readjustment will be done according to electrical performance test results. Any possible extraneous waves will be removed or be under control to the full. Based on the plane wave spectrum (PWS) theory, the direction and power level of adaxial extraneous waves can be distinguished by different incident angles. However, it will fail in distinguishing extraneous waves in the same or near direction. Under this condition, the time domain approach can be used as an aided tool.
