Abstract: 

 

The subject and purpose of the work. The need to generate high-power pulsed high-frequency oscillations and ensuring the necessary energy potential of radio engineering systems leads to the usage of magnetrons. One of the most important characteristics of a pulsed magnetron is the frequency stability of the generated oscillations, which in some cases may not provide an opportunity to obtain the necessary coverage range and necessary parameters. Therefore, the creation of frequency control systems for magnetrons is relevant. The purpose of the work is the analysis of existing methods of magnetron frequency stabilization, the development of the concept of frequency stabilization system for ultra-high frequency magnetrons, including THz.

Methods and methodology. In the article, a cutting-age method for tuning the frequency of a magnetron is selected. It is based on the use of additional bias coils. A frequency discriminator scheme combines the advantages of a single-step layout (simplicity of design and adjustment) and a push-pull layout (jam compensation). The analysis of the developed layout was carried out using the method of mathematical modeling.

Results. A system for automatic adjustment of the frequency of pulsed magnetrons has been developed.

Conclusions. As a result of the analysis of existing methods, conclusions were made about the novelty of the proposed system for automatic adjustment of the frequency of pulsed magnetrons and its advantages in comparison with the known solutions.
Keywords: automatic frequency control, discriminator, magnetron, radar system
