| 摘 要： | 数值模拟并给出了测量距离、积分角度范围和E面、H面等化性对辐射场积分功率的影响。基于X波段大功率微波源、20dB标准喇叭以及680mm辐射喇叭,开展了测量布局对辐射场积分功率的影响大功率验证实验研究。此外,基于X波段9.3,9.7GHz相对论返波管,开展了测量布局的高功率应用实验研究。研究结果表明:尽管测量距离不满足远场条件,但只要辐射喇叭E面、H面的等化性较好,通过足够的积分角度范围控制,也可以得到较为准确的辐射场功率测量结果。

| Abstract: | The measurement layout of the high power microwave in radiation field, which includes measuring the distance, the integral angle range, and the equality of E-plane and H-plane, is researched with numerical methods. The influence of measurement layout on the experimental results in radiation field is studied by the X-band magnetron and 20 dB horn as well as 680 mm horn with an input power of 407 kW. And the measurement layout is validated by the X-band 9.3 GHz and 9.7 GHz relativistic back wave oscillator. Experimental results show that accurate results can be got by the integral angle control if the equality of E-plane and H-plane is well, even though the measurement distance does not satisfy the far-field condition. |
