预警机在现代战争中发挥着重要作用,为了提高战斗机的突防能力,文中研究了基于副瓣干扰的多方位航迹欺骗干扰方法。首先,建立干扰模型;然后,对能有效达到其干扰效果的辅助决策参数进行研究计算;最后,选取典型数据对某型预警机机载雷达进行干扰仿真。结果表明:可在机载预警雷达显示终端产生多方位不同距离的密集航迹假目标,在此干扰条件下,可有效掩护飞机的突防,甚至对预警机实施有效攻击。

Early warning aircraft (EWA) plays an important role in modern war. In order to improve the fighter's penetration capability, the technology generating the radar false targets with signature of flight track based on side-lobe jamming was researched. First, the jamming model was established. Then, the parameters of auxiliary decision making problems related to the jamming effect were calculated. At last, according to the typical data, the jamming of a certain airborne early warning pulse Doppler radar was simulated. The results show that display terminal of air-borne early werning radar can generate intensive decoys, which can effectively screen fighter's penetration and even attack the EWA under jamming situdtion.
