Description
technical field [0001] The invention belongs to a test device for a high-power microwave radiation antenna system, in particular to a high-power impulse response test device for antenna surface materials. Background technique [0002] With the continuous development of high-power microwave technology, high-power microwave has broad application prospects in many fields. In order to apply high-power microwaves to the target, it is necessary to radiate the high-power microwaves generated by the high-power microwave source, and the antenna system is the key system for high-power microwave radiation. There are many traditional antenna forms, but there are not many antenna forms that can be used in the field of high-power microwaves, which are mainly limited by the radiation efficiency of the antenna, the power capacity of the antenna surface material, and the response characteristics of the antenna under short pulses. In order to determine the radiating antenna, it is first nece...
