摘　　要：针对卫星数据链的自适应调零天线在调零过程中波束形状恶化以及存在暂态响应时间等问题,分析了自适应调零天线的两种调零策略,采用基于调零策略改变干扰时间的方法,给出了4种闪烁式干扰策略,提出了一种分布式闪烁干扰方法,并对其干扰效能进行了分析。仿真结果表明,该方法能够有效干扰卫星数据链的自适应调零天线且具有较高的效费比。Two nulling methods of adaptive nulling antennas are to overcome the problem that the a- daptive nulling antennas of satellite data links have worse beam configurations and the transient re- sponse time exists during nulling. According to a method of changing jamming time based on the nulling method, four kinds of blinking jamming and distributing blinking jamming method are pro- posed, and the jamming effectiveness is analyzed. Finally, the simulation result shows the method can jam adaptive nulling antennas effectively and it has higher cost-effectiveness.
