摘要
时域编码超表面是一项可以对电磁波进行时变调制的新技术,针对该技术的调控特性,该文提出了一种基于时域编码超表面脉内-脉间编码优化的雷达干扰方法。首先分别在快时间域和慢时间域建立优化模型,通过优化脉内-脉间相位编码,实现目标能量的搬移,形成距离-多普勒二维图上的欺骗干扰。然后通过遗传算法对该离散优化模型进行求解。另外,该文从超表面编码策略的角度分析了多种调控因素对干扰效果的影响,为实现欺骗干扰的最佳策略提供指导。
Time Domain Coding Metasurface(TDCM)is an emerging technology enabling dynamic modulation of electromagnetic waves.In response to the control characteristics of this technology,this paper presents a radar jamming method based on TDCM intrapulse and interpulse coding optimization.First,optimization models are established in fast and slow time domains.By optimizing intrapulse and interpulse phase coding,the energy redistribution of targets is achieved,thereby generating deceptive interference on the range-Doppler two-dimensional plot.Subsequently,a genetic algorithm is employed to solve this discrete optimization problem.Furthermore,this paper analyzes the effect of various modulation factors on interference effectiveness in terms of TDCM coding strategies,providing guidance for achieving optimal strategies for deceptive interference.
