Presented in this paper is the investigation of some problems existing in the far - field method widely used in hpm measurement . first , the errors are analyzed from the practical calculation of the directivity for the radiation of the te11 mode in the circular waveguide . secondly , the results obtained from simulation and experiments are compared with each other on the effective area of the receiving antenna of certain types , and the power capacity are calculated for these antenna 首先,对圆波导te11主模辐射方向性系数实际计算中存在的误差进行了分析;其次,对一些型号的接收喇叭有效面积进行了模拟和实测对比,并通过计算给出了这些型号的接收喇叭的功率容量;最后,实验测定了微波脉宽对一些微波器件? ?同轴型检波器、同轴型衰减器及微波电缆性能的影响。
