摘　　要：时域自适应抗干扰是导航对抗领域最常规的抗干扰技术之一,可以通过自适应算法生成时域滤波器,在不需要先验信息的前提下应对复杂多变的窄带干扰。随着干扰环境复杂化、干扰手段扩大化,给传统时域抗干扰带来了高抗干扰性能不足、复杂度过高、测距稳健性不足的难题,时域抗干扰技术也在导航对抗升级的同时不断改进和发展。介绍了时域抗干扰的基本概念以及经典算法,对近年来时域抗干扰研究面临的主要问题进行了归纳总结,并分别从提高算法收敛性、降低硬件复杂度以及提高测距精度3个方面给出了技术发展概述。最后,根据对已有技术的总结和面临的工程问题,对未来时域抗干扰技术的发展方向做出了展望。Time-domain adaptive anti-jamming is the most conventional anti-jamming technology in the field of navigation countermeasures.Time-domain anti-jamming technology can suppress changeable narrow-band interference without prior information through adaptive algorithm.With the complexity of the interference environment and the expansion of interference methods,traditional time-domain anti-jamming has brought high anti-jamming performance,insufficient performance,and high complexity.The problem of insufficient ranging robustness,time-domain anti-jamming technology is constantly improving and developing while navigation countermeasures are being upgraded.The basic concepts and classic algorithms of time-domain anti-jamming are introduced,and the main problems faced by time-domain anti-jamming research in recent years are summarized.It also focuses on improving algorithm convergence,reducing hardware complexity,and improving ranging accuracy.The aspect gives an overview of technological development.Finally,based on the summary of the existing technology and the engineering problems faced,a prospect for the future development direction of anti-jamming technology in the time domain is made.
