基于Fraunhofer衍射理论,建立了六角形相干列阵远场分布的理论模型,采用Strehl比和能量集中度作为评价参数,分析了列阵排列方式、振幅、填充因子对远场分布的影响.并由爬山法相位控制技术和六棱台合束器,构建了七阵元光纤相干列阵实验系统.在0.66填充因子情况下,获得了Strehl比为0.70、能量集中度为0.40七阵元合成光束,以及获得了能量集中度分别为0.45和0.18的二阵元线阵和四阵元矩形阵合成光束. Based on the Fraunhofer diffraction theory, a theoretical model of the far-field distribution of hexagonal coherent array was established. The influences of array arrangement, amplitude and fill factor on the far-field distribution were analyzed by using Strehl ratio and energy concentration as evaluation parameters. The phase-controlled hill-climbing method and the hexagonal beam combiner, a seven-element optical fiber coherent array experiment system was constructed.With the 0.66 fill factor, the Strehl ratio was 0.70 and the energy concentration was 0.40 seven- As well as the two-element linear array and the four-element rectangular array with the energy concentration of 0.45 and 0.18, respectively.
