摘要
从干涉仪测向原理出发,结合干涉仪测向公式进行了测向误差分析。根据测向精度要求,提出了三基线设计及最长基线长度要求;根据最短基线解相位模糊要求,提出了八比幅测向精度要求;设计并实现了一种基于多基线干涉仪和多波束比幅联合测向的天线系统。
Direction finding error is analyzed by interferometer direction finding formula on the basis of interferometer direction finding theory in the article. Three-baseline design and the longest base- line length requirement are presented according to direction finding precision demand. Eight-ampli- tude comparison direction finding precision demand is proposed according to the demand to solute the shortest baseline phase fuzzy. An antenna system of joint direction finding based on multi-base- line interferometer and multi-beam amplitude comparison is designed and realized：
