本文在分析野战通信干扰基本态势的基础上,定义并给出了各种传输模型(包括自由空间、Rayleigh、RiCean、Longley等)下,通信系统的生存因子、抗干扰有效度和抗干扰能力指数,然后研究了抗干扰的策略和战术技术方法,最后,讨论了抗干扰系统性能评估的指标体系和评估方法。 Based on the analysis of the basic situation of field communication jamming, this paper defines and presents the survival factors, anti-jamming effectiveness and anti-interference ability index of communication system under various transmission models (including free space, Rayleigh, RiCean and Longley) , And then studied the anti-jamming tactics and tactical techniques and methods. Finally, the paper discusses the index system and evaluation method of anti-jamming system performance evaluation.
