摘　　要：本文提出了一种改进的雷达谐波辐射发射测试方法,利用该方法进行雷达谐波辐射发射测试无需校准接收天线的远场天线系数,只需考虑接收天线的远场增益。该方法根据弗里斯传输方程推导得到。测试过程首先利用矢量网络分析仪测试系统的空间传输损耗,保持测试距离不变的情况下测量接收机读数,并带入推导后的公式计算即可得到基波和谐波的等效辐射功率。该方法与现有的天线系数法测试结果进行了对比,测试结果相差1d B以内,通过对比验证了该方法的有效性。We put forward a new antenna harmonic radiated emissions outputs test method of the radars.We only consider the far-field gain of the receiving antenna without considering the receiving antenna factor.The method is derived by Friis transmission formula.We measure the air loss first by the vector network analyzer,then the receiver voltage reading under the condition the distance unchanged.The method is compared with the existing antenna factor test method.The result difference is less than 1 dB.In this case,the comparison proves that the method is effective.
