Abstract

The X-band high-power TWT is developed to meet the needs of remote detection radar. It has advantages such as high frequency and wide bandwidth, which are conducive to improving radar imaging resolution. At the same time, it also has great power potential, which can better meet the comprehensive requirements of high radar resolution and long detection range. To address the key challenge of improving the heat dissipation performance of the high-power TWT collector, this paper introduces the Finite Element Method (FEM) to carry out detailed numerical simulation and optimization of collector structure and material. The experimental results show that the designed collector structure can be successfully applied to a scientific research project, which ensures the realization of its electrical parameters, and validates the validity of the proposed approach and method.
