Embodiment 1

[0044] The cuboid shell 2 is made of polytetrafluoroethylene with a dielectric constant of 2.4, and the dimensions are Ls=304mm, Ws=40mm, Hs=5.5mm, and thickness Ts=2mm. The metal conductor tape 3 is pasted at the middle position of the inner bottom of the rectangular parallelepiped shell 2, and its length, width and height are respectively Lc=300mm, W=3mm, Tt=0.5mm. The grounding metal plate 4 has a thickness Tg of 2 mm, and is tightly fitted with the cuboid shell 2 to form a closed cavity. Pure water fills the entire cavity through an orifice valve located on the cuboid housing 2 . The metal conductor strip 3 is immersed in pure water, and is kept at a distance of 1mm from the grounding metal plate 4, wherein a cylindrical dielectric support structure 5 is arranged between the metal conductor strip 3 and the grounding metal plate 4, and its height is 1mm and the diameter is 3mm. The material is Teflon. The welding point between the metal probe 6 and the metal conductor str...

Abstract

The invention belongs to the technical field of high-power microwave measurement, and proposes an ultra-wide-spectrum high-power microwave sensor based on a water medium, comprising a water medium, a cuboid shell, a metal conductor strip, a medium support structure, a metal probe and a coaxial output port The cuboid shell is placed above the grounding metal plate, and the metal conductor strip is arranged in the middle of the bottom of the inner side of the cuboid shell; the upper part of the cuboid shell is provided with a hole valve, which is used to inject water medium to the cavity formed by the cuboid shell and the metal grounding plate. Filling; one end of the metal probe is connected to one end of the metal conductor strip through the grounded metal plate and the water medium, and the other end is connected to the coaxial output port. While ensuring the miniaturization of the sensor, the invention increases the effective measurement time window to more than 10ns, has the characteristics of good waveform fidelity performance, wide measurement frequency bandwidth, and the output waveform is the original waveform of the excitation pulse electric field, which can be applied in small spaces and realize accurate measurement of Accurate measurement of ultra-wide-spectrum electromagnetic pulses with different pulse widths.

Description

technical field [0001] The invention belongs to the technical field of high-power microwave measurement, in particular to an ultra-wide-spectrum high-power microwave sensor. Background technique [0002] Ultra-Wideband High Power Microwave (UWS-HPM, Ultra-Wideband High Power Microwave) is a kind of transient strong electromagnetic pulse without carrier frequency, the pulse width is on the order of nanoseconds, and the pulse rise / fall time is on the order of sub-nanoseconds. , its instantaneous spectral width can reach the order of hundreds of megahertz to gigahertz. Compared with the nuclear electromagnetic pulse, its rising edge is steeper, the pulse width is narrower, the frequency band is wider, and the penetrating ability is stronger, which constitutes an important component for modern electronic information systems. serious threat. In the performance test of ultra-broad-spectrum high-power microwave radiation system, it is necessary to accurately measure the UWS-HPM ra...
