摘　　要：阐述了NLFM信号的产生和脉压的基本原理,结合某雷达系统的要求,在分析比较了几种波形产生、脉压原理及实现方法的基础上、基于DDS技术和大规模可编程FPGA器件,设计了数字化的NLFM信号的波形产生及脉压处理系统、测量分析结果与模拟仿真基本吻合,可满足系统要求。This paper describes the basic principles of producing and pulse compression for the NLFM signal. After analyzing and comparing several wave evolvement, this paper designs the wave evolvement and pulse compression system of digital NLFM signal based on the DDS technology and the FPGA chips. The measurement analysis result and simulation is identical,and that satisfied with the system requirement.
