摘要
本文提出了一种基于欧拉体系的的群时延失真的抑制方法,建立可以更准确地描述空间行波管注-波互作用非线性物理过程的物理模型,获得反映注-波互作用同步状态以及反映群时延失真的非线性特性的指标参量,解释群时延失真产生的物理机制,提出抑制群时延失真的方法,为L波段空间行波管高线性度的实现提供理论方法和技术支持。
In this paper,a group delay distortion suppression method based on Euler system is introduced.The physical model which can describe nonlinear physical process of the space traveling-wave tube(TWT)beam-wave interaction more accurately is established,and the indicators reflecting the beam-wave interaction and the nonlinear characteristics of group delay distortion are obtained.The physical mechanism of group delay distortion is explained,and a method for group delay distortion suppression is proposed.This paper provides theoretical method and technical support for the realization of high linearity of L-band space TWTs.
