Abstract

The invention belongs to the technical field of microwave pulse compression and relates to an energy storage switching method microwave pulse compression device with high energy extraction efficiency.The device comprises an input waveguide, an input coupling diaphragm, a resonant cavity, a self-breakdown switch, a sliding short circuiting device and a waveguide HT structure. The input waveguide is connected to the input coupling diaphragm, the input coupling diaphragm is connected to the resonant cavity, a right end of the resonant cavity is connected to the sliding short circuiting device, the self-breakdown switch is placed in the resonant cavity, a side of the resonant cavity is connected to the waveguide H-T structure, and an extraction chamber is set between the waveguide H-T structure and an output waveguide of the waveguide H-T structure. The energy storage switching method microwave pulse compression device with high energy extraction efficiency has the advantages that the microwave reflection generated by the waveguide H-T structure can be effectively offset by adding the extraction chamber between the waveguide H-T structure and an output waveguide, therefore, the energyextraction efficiency and power gain of the energy storage switching method microwave pulse compression device are improved, and the adding of the extraction chamber structure does not affect the resonant frequency and quality factor of the resonant cavity.

technical field [0001] The invention belongs to the technical field of microwave pulse compression, and relates to a microwave pulse compression device with high energy extraction efficiency and energy storage switching method. Background technique [0002] Microwave pulse compression technology is an effective means to obtain high-power microwave output. The main technical approach is to first input long-pulse low-power microwave pulses into high-quality factor resonant cavities to store energy, and then quickly extract energy from the resonant cavities. Thus realizing microwave power amplification. Typical microwave pulse compression techniques include: energy doubler method (SLAC EnergyDoubler, SLED), power binary doubling method (Binary Pulse Compression, BPC), delay line distribution method (DelayLine Distribution System, DLDS) and energy storage switching method (Switched Energy Storage, SES). Among them, energy storage switching pulse compression technology is widel...
