摘要

为了兼顾在内场与外场测试与验证不同项目中雷达导引头的抗干扰性能,设计了一款设置灵活、参数可调的数字式宽带噪声干扰源。以FPGA和DDS专用芯片为核心,通过伪随机序列产生与DDS芯片控制,完成了噪声调频信号产生和可编程宽带干扰源的设计,在满足高速、高性能的同时,具备了较强的灵活性和可靠性。使用MATLAB软件对噪声调频干扰信号的每一步实现过程进行了仿真与分析,验证了方案的可行性。

Abstract

For the sake of the test and verification on Radar seekers of different projects in both infield and outfield, a digital wide-band noise jammer with flexible settings and adjustable parameters is devised. With FPGA and DDS dedicated chip as the core, the noise frequency modulation signal is generated, and the design of a programmable wide-band jammer is completed through pseudo-random sequence generation and DDS chip control. In addition to having high speed and high performance, the proposed design also has strong flexibility and reliability. Using MATLAB, Each step of the implementation progress is simulated and analyzed, and the feasibility of the scheme is verified.
