Embodiment Construction

[0029] Now in conjunction with embodiment, accompanying drawing, the present invention will be further described:

[0030] The scheme of the embodiment of the present invention is: composed of a radome tube body with a high airtight level, an adjustment rod, an adjustable discharge electrode, a disc cone and a radiation oscillator, such as figure 1 shown.

[0031] The two ends of the radome tube body 4 fix the end plate 2 through the flange plate 3, and the middle part of the end plate 2 is provided with an input terminal 1; Fixed disc cone 6, a plurality of radiation oscillators 5 (such as figure 2 shown) and disc cone 6 (as image 3 As shown), the multiple through-holes on the panel are connected by threads; the adjustment of the output frequency of the radiator is realized by installing vibrators of different lengths (the vibrator lengths of a single installation are the same) on the disc cone.

[0032] The discharge electrode 7 is located in the middle of the disc cone...

Abstract

The invention relates to a high-power radiator with adjustable frequency. The radiator with adjustable center frequency can be realized by changing the length of the antenna vibrator, the discharge distance and the air pressure. Combined with the charging power source and the pulse power source platform, different frequencies can be output in the same system. Radiation field of high power electromagnetic pulses. Compared with ordinary high-power broadband antennas, the present invention has the following characteristics: 1. Adjustable radiation frequency: under the excitation of the same pulse power source, the adjustment of the radiation frequency can be realized by replacing the vibrators with different lengths in the radiator without using Different power sources reduce the requirements and costs of EMP effects testing. 2 Adjustable discharge spacing: By setting the electrode spacing of the discharge switch to be adjustable outside the radome, the array of radiators can be realized and a higher radiation field strength can be obtained.

Description

technical field [0001] The invention belongs to a high-power pulse compression and electromagnetic radiation device, and relates to a high-power radiator with adjustable frequency. It compresses the high-voltage pulse fed into it through its own structure, converts the voltage pulse into a radio frequency pulse, and realizes the transmission into space. effective radiation device. Background technique [0002] When conducting damage effect tests of electromagnetic pulses on electronic equipment, it is necessary to replace high-power radiation sources with different center frequencies in order to obtain the sensitive frequency and damage threshold of the target. In order to obtain test data, various radiation systems are required. On the one hand, high requirements are placed on the area of ​​the test site, and on the other hand, the cost of the test is also increased. Therefore, a high-power radiation system based on a frequency-tunable radiator is very necessary for electr...
