Abstract

The invention provides a device and a method for acquiring ultrahigh repetition frequency high-power microwaves based on a pulse compression technology. According to the method, an arbitrary waveform generator is adopted to cyclically generate a specific coding microwave long pulse string with a mu s magnitude period, the specific coding microwave long pulse string is subjected to power amplification through a microwave power amplifier, a specific coding microwave long pulse string with a kW magnitude power is output, and then the specific coding microwave long pulse string passes through a pulse compression reverberation chamber. The specific coding microwave long pulse string with the cycle of mu s magnitude and the power of kW magnitude is compressed into a microwave pulse string with the pulse width of ns magnitude, pulse width compression is achieved, the peak power is greatly increased from the kW magnitude to hundreds of kW or even MW magnitude, and generation of MHz magnitude ultrahigh repetition frequency high-power microwaves is achieved. According to the ultrahigh repetition frequency high-power microwave generation device and method, a microwave switch is not adopted, and the device and method have the advantages that the center carrier frequency, the pulse width and the pulse repetition frequency are flexible and adjustable.

Problems solved by technology

At present, how to increase the repetition frequency of output microwave pulses is one of the important development directions in the field of high-power microwave technology research. At this stage, the method of generating ultra-high repetition frequency high-power microwave pulses above 100 kHz is mainly in the field of ultra-broadband high-power microwave Realized, but limited by its antenna radiation characteristics, its interference distance is short, it is difficult to realize the original distance application

Narrow-spectrum high-power microwave antennas usually have a large gain and have great advantages in long-distance applications, but limited by the way high-power microwaves are generated, their repetition frequency usually does not exceed 100 Hz, and it is difficult to achieve a repetition frequency of more than 100 kHz
