Embodiment Construction

[0065] figure 1 Is the overall flow chart of the present invention; as figure 1 Shown, the present invention comprises the following steps:

[0066] The first step is to construct a light-guided adaptive narrow-band microwave generator, such as figure 2 As shown, the photoconductive adaptive narrow-spectrum microwave generator is composed of two parts: a circuit modulation module and an optical path modulation module. The optical path modulation module is a high-energy pulse cluster laser that can be used as a signal source for a microwave system photoconductive device, referred to as a high-energy pulse cluster laser. The circuit modulation module is composed of three parts: a voltage source 200 , a wide bandgap semiconductor device 400 and a radiation output component 300 . The high-energy pulse cluster laser is connected to the wide bandgap semiconductor device 400 by optical fiber or optical waveguide.

Abstract

The invention discloses a light guide self-adaptive narrow-spectrum microwave generation method based on high-energy pulse cluster laser, and aims to solve the problems of large size of a microwave generation device, single frequency point and difficult frequency modulation in an existing microwave generation method. According to the technical scheme, a light guide self-adaptive narrow-spectrum microwave generator composed of a high-energy pulse cluster laser device, a voltage source, a wide-band gap semiconductor device and a radiation output assembly is constructed firstly; the high-energy pulse cluster laser device outputs the high-energy pulse cluster laser adjustable in pulse cluster repetition frequency, pulse width, envelope waveform and GHz high-frequency pulse repetition frequency to the wide-band gap semiconductor device; the voltage source is a solid-state pulse forming line, and generates a pulse voltage to act on the wide-band gap semiconductor device; the wide-band gap semiconductor device generates a high-frequency electric signal under the simultaneous action of the laser and the voltage; and the radiation output assembly is used for radiating the high-frequency electric signal and outputting a microwave signal. By adopting the method, the problems of large size of the microwave generation device, single frequency point and difficult frequency modulation can be solved.

Description

technical field [0001] The invention relates to a high-power microwave generation method—a narrow-spectrum microwave generation method based on high-repetition-frequency pulse laser and wide-bandgap photoconductive semiconductor. Background technique [0002] Through strong electromagnetic radiation, high-power microwave interferes, disrupts, and damages the electronic information system of equipment, degrading or invalidating its function, and can effectively improve information countermeasures. [0003] In order to cope with the increasingly complex electromagnetic environment of threat targets in the field of information technology and the continuous emergence of new waveforms and new spectrums, it is urgent to develop a new adaptive directed energy microwave generation method with flexible and adjustable parameters. Traditional high-power microwave generation methods are based on pulsed power devices and relativistic electric vacuum devices, which have been developed for...
