高频雷达海洋回波信号的混沌特性研究, 对喜欢研究混沌海杂波的用户很有益-Chaotic study on HF radar sea clutter

本文对充电机功率特性和谐波特性进行详细分析，在MATLAB/Simulink软件平台上对高频充电机/站进行仿真，为高频充电机谐波治理方案的给出提供依据。在了解谐波特性的基础上，采用可以动态补偿谐波和无功功率的有源电力滤波器（Active Power Filter, APF）实现对充电机/站的谐波抑制。-In this paper, the harmonic characteristic of non-sinusoidal circuit is analyzed in detail. And on

Abstract The key of developing high frequency wideband communication system is how to model the HF wideband channel. Some HF wideband models are discussed and compared in this paper, including Vogler model, parallel subband model, two impro
