摘　　要：针对实际工程应用中,当工作频段过高时,均匀线阵MUSIC测向算法所需的天线间距过小,小于有一定增益要求和波束宽度要求时能达到的天线尺寸,难以适用于实际工程的不足,研究了阵元间距足够大、阵列测向无模糊、检测概率足够工程系统应用的可对两相干信号来波方向进行解算的非均匀线阵配置技术。In the actual engineering application,when the working frequency band is too high,the space between antenna elements required by the uniform linear array MUSIC direction finding(DF)algorithm is too small,even smaller than the size of antenna with definite gain requirement and beam width requirement,so the antenna is difficult to apply to the actual engineering.Aiming the problem,this paper studies a nonuniform linear array configuration technology to calculate the direction of arrival for two coherent signals which not only has sufficiently large element space and unambiguous arry DF ability,but also has enough detection probabilities for engineering system applications.
