摘要
介绍了一种雷达干扰系统的设计方法。该干扰系统以线性调频(LFM)脉冲预警雷达为主要研究对象,以新一代小型雷达欺骗干扰机为应用背景。通过分析雷达目标回波信号形式和假目标参数的设定依据,结合以FPGA实现DDS(Direct Digital Synthesize)的方法在调幅调相方面的优势,利用高性能DSP(Digital Signal Processor)和FPGA,提出了一种基于DDS技术的线性调频脉冲雷达干扰系统设计方案。该系统能够产生多个假目标回波信号,干扰雷达系统的正常检测判断,具有十分重要的实用价值。
In this article a design method of radar jamming system is introduced. This jamming system＇s research object is LFM pulsed pre-alert radar, and its application background is our nation＇s new generation radar deception jamming equipment. After analyzing the signal formula of radar target＇s echo and the parameters of false-target, using FPGA and DSP,a DDS based LFM pulsed radar jamming plan is brought out with the advantage of the DDS＇ realizing method based on FPGA. This system has the ability to generate multi-false-target signal, jam LFM pulsed radars. This is valuable in application.
