第一部分 A、引言本讲仍将沿用上讲的形式详细介绍天线的各种电子抗干扰技术。从电子抗干扰角度考虑,天线设计应满足以下要求: ——频率捷变雷达要求宽带; ——在大频率范围内要求低旁瓣; Part I A, Introduction This talk will continue to introduce the various forms of electronic anti-jamming antenna technology. From an electronic interference point of view, the antenna design should meet the following requirements: - Frequency agile radars require wideband; - Low sidelobes are required over a large frequency range;
