摘要
为改进线性调频雷达系统所采用的在单色频率点附近扩谱抗干扰技术,加强制导雷达站具备抗有源、无源干扰,反侦察,抗硬杀伤的反幅射导弹和反隐身的能力,通过将单频点扩谱改为多频点扩谱跳谱,实现了高抗干扰信号处理系统,给出方案中在中频段实现的线性调频信号产生方法以及对应的匹配滤波处理系统。样机测试结果证明设计是成功的。
To improve anti-jamming technique by spread spectrum close to monochromatic frequency, so that enhance the ability of anti-active-jamming and anti-passive-jamming, anti-reconnaissance, anti-radiation missile, anti-stealth, by means of multi frequency spread spectrum and hopping spectrum instead of mono-frequency spread spectrum, realizing strong processing system for anti-interference signal, providing the method of generating of Chirp signal and corresponding matched filter system. Test results on sample machine prove that design is a great success.
