Development of array device for power measurement of high power microwave radiation field

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.
