摘　　要：为了满足甚高频(VHF)有源相控阵雷达数据高效传输,采用了以DSP,Lwip实现网络数据传输;进行了传输效率理论分析和仿真计算,主要仿真了运算速率、数据包大小、UDP/TCP和DSP主频对传输速率的影响,分析了运算速率、数据包大小、UDP/TCP和DSP主频对数据传输的影响因素,提出了阶梯型数据处理模式、固定字节报文传送格式和TCP协议的综合方法。创新地把嵌入式网络接口应用到甚高频有源相控阵雷达上,并满足相控阵雷达数据传输速率的高效性要求;成为整个系统数据传输软件开发的理论指导。In order to meet the requirement of efficient data transmission of very high frequency （VHF） active phased ar-ray radar, DSP and Lwip was applied to achieving network data transmission. The theoretical analysis and simulation calcula-tion of transmission efficiency were conducted. The influence of the operational rate, packet size, UDP/TCP and DSP domi- nant frequency on transmission rate was simulated. The factors of affecting data transmission were analyzed. The step data processing mode, the fixed-byte packet transmission format and TCP protocol are proposed in this paper. The embedded net-work interface was innovatively applied to VHF active phased array radar. The innovation meets the efficiency requirements of VHF active phased array radar. The achievement has become a theoretical guidance for developing the data transmission soft- ware of overall system.
