摘要

磁控管自激振荡特征可用于自激放大类辐射源的"指纹"识别

本文采用粒子仿真方法对磁控管的经验电路模型及其所得特征进行了仿真分析.首先由磁控管的Slater模型推导了自由振荡和受控振荡下的瞬态解和稳态解

据此得到频推系数、自激指数、受控振荡稳态解等特征.然后建立了磁控管的粒子仿真模型

在单模工作状态下进行了自由振荡仿真分析

以验证频推系数特征和自激指数特征;进行了受控振荡的仿真分析

以验证频推系数特征以及受控振荡稳态解特征.仿真分析结果证明了上述特征的可行性.

Abstract

The feature of magnetron exciting process can be used in the Specific Emitter Identification of self-oscillatory emitters.In this paper

a Particle In Cell (PIC) simulation was taken to verify a magnetron’s empirical circuit model and the features derived.At the beginning

the Slater circuit model was given

based on which the transient and steady solutions of the free and controlled oscillations were derived.Then the pushing coefficient feature

self-excitation exponent feature and the steady solution feature were presented.After that

a magnetron PIC simulation model was set up.Using the model

a free oscillation process was simulated to verify the pushing and exponent features.A controlled oscillation process was simulated to verify the pushing and steady solution features.The analysis results prove the effectiveness of the features.
