摘要
多站雷达协同虽然能利用多视角探测和信息融合处理有效提高抗干扰能力,但实际场景下既很难满足其需要的探测条件,又往往面临着组网被摧毁的风险,所以单站雷达的抗干扰能力仍需提升.针对单站雷达探测视角单一,得到的回波信息有限,抗干扰能力不足等问题,通过在单站雷达回波接收过程中加入可配置智能超表面(Reconfigurable intelligence surface,RIS)构造分布式探测条件,接收目标多方向散射信号,从而开辟单站雷达抗欺骗式干扰的新途径.仿真结果表明,加入RIS能有效地构建虚拟通道,能有效提高单站雷达的抗干扰能力.
Abstract
Although multi-station radar cooperation can effectively improve the anti-jamming ability by using multi-view detection and information fusion processing,it is difficult to meet the detection conditions in the actual scene,or it suffers from the risk of network destruction in practice.Therefore,it is still necessary to improve the anti-jamming ability of single station radar.Aiming at problems of single-station radar,such as single detection angle,limited echo information and insufficient anti-jamming ability,a distributed detection condition is constructed by adding a reconfigurable intelligence surface(RIS)in the echo receiving process of single-station radar to receive the multi-directional scattering signal of the target,thus opening up a new way for the single-station radar to resist deceptive jamming.Simulation results show that adding RIS can effectively construct virtual channel and improve the anti-jamming ability of single station radar.
