摘　　要：核电磁脉冲武器对工作在战场中的电子设备危害巨大,为确保电子设备在复杂的战场电磁环境中可以正常工作,需要对其进行辐射测试。针对系统级电磁脉冲测试需求,文中提出了一种CW辐射装置的设计方法。通过对辐照器的辐射振子进行结构设计与加载设计并结合计算工具MATLAB,给出了一种工作频段为100 kHz^500 MHz的水平极化CW辐照器的设计方法。设计结果表明,在100 kHz^10 MHz的频段内,辐照器振子形状变化对于测试区域的场分布影响较小;当辐照器振子加载增加数倍时,测试区域空间波阻抗也增加相同倍数。Nuclear electromagnetic pulse weapon is harmful to the electronic equipment in the battlefield.Radiation test is necessary for the aim of ensuring the capability of electronic equipment in complex electromagnetic environment.In this study,a design method of CW illuminator was presented to meet the requirement of system level electromagnetic pulse test.A design method of horizontally polarized CW illuminator element working frequency range from 100 kHz to 500 MHz was presented by means of the structure design and loading design as well as the combination of MATLAB.The design results indicated that in the frequency band of 100 kHz^10 MHz,the shape change of the illuminator element had little influence on the field distribution in the test area.Besides,when the oscillator vibrator was loaded several times,the spatial impedance of the test area was also increased by the same factor.
