摘要: 针对杜惠平(1999)提出的一种基于菲涅尔区修正结构聚焦的多波束自适应天线,引入一个统一的模型,通过与均匀线形阵列的比较和分析,说明了这种自适应天线的阵列输出特性兼有均匀线形阵列和多波束天线二者的特点。计算机模拟结果表明,利用这种天线可以有效地完成自适应处理。Abstract: It is suggested by Du Huiping(1999) to construct a novel multiple-beam adaptive antenna with Fresnel zone phase-correcting focusing configuration and feeding-array. In order to discover the operating mechanism of this new adaptive antenna, under a comparable uniform model, statistical characteristcs of feeding-array output, is analyzed by comparison between FMBA and ULA. Qualitative analysis shows that this type of adaptive antennas can realize adaptive signal processing effectively.
