摘要
首先分析了基于菲涅尔区聚焦多波束天线的信号处理特点，在与基于均匀线形阵的空间谱估计性能比较的基础上，讨论了菲涅尔区聚焦多波束天线波达方向估计的性能；最后利用多信号分类法进行波达方向估计的计算机模拟，并定量地分析了数值结果。
With discussion on the signal transformation from spatial spectral to focal fields distribution caused by Fresnel Focusing Configuration, a new adaptive antenna constructed by Fresnel Zone phase correcting plate and feed array is analyzed in detail. Then, the MUSIC method is exploited to perform computer simulations, and performance of Direction of Arrival estimation is analyzed quantitatively. In Comparison with that of the uniform spaced linear array the analysis and the simulation results suggests that the one proposed here is distinguished itself.
