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...

The embodiment of the invention provides an X-waveband high-power pulse compression device and a power transmitter. The pulse compression device comprises pulse compressors sequentially connected through a pulse transmission part 1. Each pulse compressor comprises a pulse compression section 4, a transition section 3 and a mode conversion section 2, and wherein the transition section 3 and the mode conversion section 2 are arranged at the two ends of the pulse compression section 4. According to the technical scheme, the structure is compact, power compression grain of 28.5 times can be achieved, and the problem that single-end pulse compression waveguide cannot achieve engineering conveniently due to length limit is solved through a three-section compression mode.
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...
