摘要: 針對(duì)杜惠平(1999)提出的一種基于菲涅爾區(qū)修正結(jié)構(gòu)聚焦的多波束自適應(yīng)天線(xiàn),引入一個(gè)統(tǒng)一的模型,通過(guò)與均勻線(xiàn)形陣列的比較和分析,說(shuō)明了這種自適應(yīng)天線(xiàn)的陣列輸出特性兼有均勻線(xiàn)形陣列和多波束天線(xiàn)二者的特點(diǎn)。計(jì)算機(jī)模擬結(jié)果表明,利用這種天線(xiàn)可以有效地完成自適應(yīng)處理。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.
