摘　　要：针对高频电路辐射干扰近场测试预估方法较多,目前没有统一的测试方法和要求,据此对比研究了基于电流驱动模型辐射预估方法和基于射频电流参数测量的辐射预估方法,并给出了相应的理论分析和实验数据.其结果表明:两种方法的预估结果与电波暗室测量结果吻合较好,但在不同频段两种方法的估计精度不同,为进一步改进辐射电磁干扰预估方法提供了依据.In view of many kinds of near field test and estimate methods in radiated interference of the high-frequency circuit existing, there is no unification test method and request at present. We have a comparative study on the estimate methods in radiated interference based on the current actuation model and radio-frequency current parameter survey and also given the corresponding theoretical analysis and experimental result. The experimental result shows that the test re- sults of the two kinds of estimate method are in agreement with the result of test in anechoic chamber. The effective reference is provided for the later high frequency radiated interference＇s estimation and the diagnosis work.
