Embodiment Construction

[0025] Now in conjunction with embodiment, accompanying drawing, the present invention will be further described:

[0026] The technical scheme of the embodiment of the present invention is: the high-power wide-spectrum disc cone antenna is composed of a discharge switch, a disc structure and a cone-shaped vibrator, such as figure 1 . Among them, the label 1 is a conical vibrator, which is marked with a grid-like shadow; the label 2 is a disc structure, which is marked with a right slash shadow; the part marked with a black thick circle is a discharge switch, which is composed of two discharge electrodes with a certain gap. structured as figure 2 . The discharge electrode is closely matched with the disc structure through the thread structure, so that the electrode is close to the disc structure, and the effect after the cooperation is as follows: figure 1 . In the work, firstly, the voltage pulse output reaches a certain amplitude, so that the switch electrode is turned ...

Abstract

The invention relates to a high-power discone antenna. A disk-shaped structure is arranged between two conical oscillators. Discharge electrodes are arranged in the center of the disk-shaped structure and tightly cooperate with the disk-shaped structure. Opposite parts of the two discharge electrodes are hemispherical structures. By a high-voltage gas switch structure at an excitation end of the high-power discone antenna to sharpen input voltage pulse, the sharpened voltage pulse excites the discone antenna to operate and radiates outwards high-power electromagnetic pulse. By integrating dual functions of sharpening pulse and enhancing radiation energy, the high-power wide-spectrum discone antenna has excellent radiation performance, and design space of a sharpening switch is saved in the design of a high-power wide-spectrum system. The antenna is convenient to use, is safe, has low experimental cost and is simple to debug. The antenna can actually be applied in fields of various high-power electromagnetic pulse researches and the like, and can be used as an electromagnetic pulse radiator of a system.

Description

technical field [0001] The invention belongs to a high-power electromagnetic pulse radiation device, in particular to a high-power disc-cone antenna, Background technique [0002] In the high-power electromagnetic pulse technology, due to the limitation of the pulse source technical conditions, the rising edge of the input voltage pulse is not steep enough, and the energy is distributed at a low frequency, so it is not suitable for directly exciting the antenna to work. Generally speaking, the voltage pulse generated by the pulse source needs to be sharpened by one or more stages of sharpening switches before the antenna can be stimulated to work, so as to meet the radiation factor required by the design. In addition, due to the complex structure of the high-power electromagnetic pulse radiation system, the voltage pulse often needs to be sharpened before exciting the antenna, so the design space reserved for the radiation antenna is small. Therefore, the high-power electro...
