Embodiment Construction
[0025] In order to make the technical solutions and advantages in the embodiments of the present application clearer, the exemplary embodiments of the present application will be further described in detail below in conjunction with the accompanying drawings. Apparently, the described embodiments are only part of the embodiments of the present application, and Not an exhaustive list of all embodiments. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.
[0026] The core idea of this solution is to replace the traditional entire helical waveguide structure with a three-stage compression method, so that the power compression gain of the pulse compression device can be increased to 28.5 times. The pulse compressor is a key component for upgrading a wideband high peak power transmitter to a narrowband higher peak power transmitter. Due to the increase in the compress...

An X-band high-power pulse compression device and a power transmitter are provided in an embodiment of the present application, wherein the pulse compression device includes: a pulse compressor sequentially connected through the pulse transmission part 1; the pulse compressor includes: a pulse compression Section 4 and the transition section 3 and mode changing section 2 which are arranged symmetrically at both ends of the pulse compression section 4 . The technical solution described in this application is not only compact in structure, but also can achieve a power compression gain of 28.5 times. The three-stage compression method solves the problem of inconvenient engineering of single-ended pulse compression waveguides due to length limitations.
Description
technical field [0001] The present application relates to the field of pulse compressors, in particular to an X-band three-section triple-fold structure helical waveguide pulse compression device. Background technique [0002] High-power microwave sources are one of the key technologies of high-power microwave weapons, and their development and application requirements have been continuously increasing in recent years. In particular, strict requirements have been put forward on the power, volume, weight and other indicators of microwave sources, and new generation methods need to be explored. High power microwave method. [0003] At present, foreign research institutions have completed the design and testing of a whole section of triple-folded helical waveguide. The measured maximum pulse compression peak power is magnified by 25 times, and the length of the whole section of helical waveguide is 2.55m. In China, the pulse compression waveguide mainly focuses on the simulati...
