Embodiment Construction

[0020] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0021] In an embodiment of the present invention, an oblique cone-shaped monopole nuclear electromagnetic pulse simulator antenna is provided, which includes a rounded frustum-shaped bracket, and several radiation cables are evenly arranged on the side of the rounded frustum-shaped bracket, and a non-metallic bracket is also included. The rounded truncated truncated support is obliquely fixed by the non-metallic support, and the central axis of the rounded truncated truncated support forms an angle of 18-22 degrees with the vertical direction. The rounded truncated bracket is made of aluminum alloy...

Abstract

The invention discloses an obliquely standing cone-shaped monopole nuclear electromagnetic pulse simulator antenna, which comprises a rounded table-shaped bracket, a number of radiation cables are uniformly arranged on the side of the rounded table-shaped bracket, and a non-metallic bracket, which is passed through a non-metallic The support obliquely fixes the rounded table-shaped support, and the central axis of the rounded table-shaped support forms an angle of 18-22 degrees with the vertical direction. The rounded frustum-shaped bracket is adopted, and several radiation cables are arranged around the side of the inverted rounded frustum-shaped bracket. The sub has good broadband characteristics and can effectively radiate the energy of the nuclear electromagnetic pulse simulator. The radiating cable with a linear structure greatly reduces the weight and wind resistance of the antenna, and is also easy to install and has better environmental adaptability.

Description

technical field [0001] The invention belongs to the technical field of nuclear electromagnetic pulse radiation simulation, and in particular relates to an oblique cone-shaped monopole nuclear electromagnetic pulse simulator antenna. Background technique [0002] Simulating nuclear electromagnetic pulse radiation is a necessary means to carry out research on nuclear electromagnetic pulse effects and verification tests. Since the nuclear electromagnetic pulse has a wide spectrum and rich low-frequency components, the nuclear electromagnetic pulse radiation waveform according to the IEC standard ranges from a few kHz to GHz, and the main energy is concentrated below 300MHz, so a relatively large broadband antenna is required for radiation. There are many types of radiators for nuclear electromagnetic pulse simulators. Common ones include bounded wave simulators, vertical monopole simulators, horizontal dipole simulators, and composite simulators. Different types of radiators pr...
