摘　　要：为满足现代电子干扰对噪声调频信号源低功耗、快速和灵活可控的要求,采用基于Wallace算法的一种直接快速生成算法,提出了一种运算量小、速度快和全数字结构的可配置噪声调频信号发生器系统设计方案。系统利用正态分布的可加性直接生成高斯白噪声随机变量,采用数字频率合成(DDS)技术完成调频功能,通过内置串行接口配置发生器参数和输出系统运行状态信息。同时,提供了基于FPGA的系统实现方案,其生成信号波形具有严格的相干性和可控性,且对外界环境不敏感。An architecture of the FM noise signal generator based on a fast direct generating algorithm referring to Wallace algorithm, of which the implementation is low power consuming, high performance and configurable, is first proposed to meet the needs of electronic jamming. Gaussian white noise is directly generated by means of the addition of the independent norm random variables, and DDS-tech is applied to FM. Control computer can perform a real-time configuration and observation by the UART interface which is inside. As well, the implementation is provided in FPGA, which is controllable and robust.
