摘要
菲涅尔区相位修正平板聚焦结构有着一些新的特点，从而可作为聚焦元件构成多波束天线［３］。该文在基于菲涅尔区相位修正平板结构的多波束天线模型下，利用多信号分类（ＭＵＳＩＣ）算法实现了对一维平面内来波方向的估计。通过计算机模拟及对模拟结果的讨论，比较了分别采用噪声子空间和信号子空间进行来波方向估计时的结果。
With the Multiple Beam Antenna constructed by Fresnel Zone phase correcting Plate(FZP) focusing element and uniformly spaced feeds array, Multiple Signal Classification(MUSIC) estimation method is exploited to perform the 1 dimensional DOA estimation.Computer simulations are prensented and discussed to show the performance of this antenna system.
