摘要: 基于高功率微波辐射场分布积分方法，通过衰减、延迟、合路等技术手段，研制了一套高功率微波辐射场功率阵列测量实验装置。该装置仅利用一台示波器就可以同时测得16个不同点处的高功率微波辐射场波形，由此得到不同点处的功率密度，在辐射天线方向图旋转对称的条件下，利用编写的程序可以迅速求得单次、短脉冲高功率微波源的空间辐射功率，并在X波段相对论返波管高功率微波源功率测试中得到应用，为高功率微波功率测量特别是单次HPM功率测量，提供了一种新的功率测量阵列装置。Abstract: Based on the distributing integral way of high power microwave(HPM) radiation field and the way of attenuation, delaying and combining, an array device for power measurement of HPM was developed. 16 HPM radiation waveforms displayed in one oscillograph and the power density of different position can be attained by this experiment device simultaneously. Under the hypothesis of axially symmetric radiation patterns, the radiation power of single short pulse HPM source may be numerated using compiled language. The device has been applied to the power measurement of X-band BWO HPM source.
