Abstract

The invention relates to the field of microwaves, and relates to a microwave source for frequency-locked scanning. The problems that in the prior art, a solid-state microwave source used as an interference source is relatively low in output power and high in cost are solved. The microwave source comprises a magnetron, and an external injection signal is connected by a circulator. According to theinvention, standing wave interaction is used as a theoretical basis, the magnetron microwave source is innovatively used as a solution idea, and a swept-frequency signal of a low-power solid-state microwave source is used for carrying out injection locking on the magnetron, so that large frequency sweeping output bandwidth and high transmitting power of the magnetron are realized. Therefore, sweepfrequency interference to spread spectrum communication systems such as unmanned aerial vehicles is provided, and the microwave source is low in cost, high in power and high in efficiency.

Description

technical field [0001] The invention relates to the field of microwaves, in particular to a frequency-locked and scanned microwave source. Background technique [0002] Microwaves are widely used in daily life, as well as experimental research in physics, chemistry, biomedicine and other disciplines. In many cases, microwave ovens are used for heating or microwave spectrum effects are used for corresponding processing. [0003] As a kind of microwave source, the magnetron's output spectrum will be affected by the anode current of the magnetron, that is, when the anode current is at a small value, it will generate clutter, phase noise or cause the output spectrum of the magnetron to be wide; [0004] Magnetron has shown its advantages because of its many advantages such as large output power, high efficiency, small size, and low cost. This makes the magnetron not only applicable to the military field, but also widely used in civil fields such as industry, agriculture, medic...
