摘　　要：本文构建了一种大功率网络模型,通过电流源对该网络进行冲击能够形成标准的罗兰C波形。文中分别对标准罗兰C电流波形的前沿阶段和后沿阶段的合成原理进行了分析计算,同时仿真了网络模型在不同负载条件下的输入/输出特性,结合理论计算与仿真分析提出了较优的网络模型配置参数,并对适配天线的负载特性提出了设计要求。为罗兰C发射机系统的工程化研制提供理论及仿真设计支撑。In this paper,a high-power network model is constructed.The standard Loran-C waveform can be synthesized by striking the network with a current source.This paper analyze the synthetic principle of the leading and lagging edge of the standard Loran-C waveform respectively,then simulate the input/output characteristics of the network model in different resistance conditions.According to the calculation and simulation results,the network parameters and the appropriate antenna resistance characteristics are proposed.The theories and simulation results in this paper support the Loran-C transmitter system engineering development.
