【摘要】 现代通信技术的日益发展,对通信干扰技术提出了严峻的挑战。针对通信干扰技术的发展趋势,提出了一种基于FIR数字滤波器组的宽带数字阵列干扰技术,阐述了该宽带干扰系统的基本组成、工作流程及涉及到的关键技术,如宽带校准技术和宽带波束形成技术。该干扰系统可以实现对常规通信电台、数据链、TACAN、IFF的宽带和多波束多目标同时干扰,大大提高了干扰系统的作战能力,最后对该宽带干扰系统进行了干扰效能评估。更多还原

【Abstract】 With the development of modern communication technology,the communication jamming technology faces the challenges. Aiming at the development trend of the communication jamming technology,this paper proposes a wideband digital array jamming technology based on FIR digital filter banks. The basic composition,operation flow and the concerned key techniques are introduced,such wideband calibration technique and wideband beamforming technique. This jamming system can implement wideband,multi-beam and multi-target jamming for conventional communication radio station,data link,TACAN and IFF,which enhances significantly the operational effectiveness. The jamming effectiveness evalutation is performed for the wideband jamming system.更多还原
