摘要
数字射频存储技术实现兼具欺骗干扰和噪声干扰特点的灵巧噪声干扰,其应对旁瓣消隐和旁瓣对消等雷达抗干扰措施的效果不佳。为解决该问题,文中在分析现代雷达有源噪声干扰工作机理的基础上,结合目标回波航迹相关技术,设计了一种将速度拖引欺骗和卷积调制灵巧噪声相结合的新型干扰信号形式,以增强兼具欺骗和噪声压制干扰的灵巧噪声干扰效果和应对抗干扰措施的能力。仿真实验验证了该干扰信号形式的有效性。
Using digital radio frequency memory） DRFM） technology to realize deception jamming and noise characteristics of smart noise jamming, good effects can not be achieved from the side-lobe blanking and sidelobe cancellation of radar anti-jamming meas-ures. To solve the problem, based on the analysis of working mechanism of modern radar active noise, combining with the target echo track-related technology, a speed drawing-out cheat and convolution modulation combined new type of smart noise jamming signal form is designed, in order to enhance both smart noise jamming effect of deception and noise suppressing jamming and respond to the ability of anti-interference measures. Simulation results verify the effectiveness of the jamming signal form.
