摘要
步进频雷达的频率跳变和相关处理特性使得传统的噪声干扰的利用效率下降,必须寻找新的干扰样式。分析了步进频信号的一维成像原理和模糊函数性质,根据步进频雷达信号处理的特点,提出了对其灵巧干扰样式的建模方法,由此得出了几种典型的和特殊的干扰样式,并对干扰效果进行了仿真分析。理论和仿真结果表明:相较于传统的噪声干扰,灵巧干扰能更加有效地实施干扰。
Due to its frequency agility and coherent signal processing,stepped-frequency radar makes efficiency of traditional noise jamming declined,so that new type of jamming must be found. Imaging principle and signal processing method and fuzzy function of stepped-frequency signal are analyzed,according to characteristics of this signal,method of modeling of its smart jamming types is proposed,via this,some typical and special type of jamming are elicited,and interference effect are analyzed by simulation. Theory and simulation result show that compared to traditional noise jamming,smart jamming is more effective.
