摘要
首先分析频率响应与波束响应的对应关系,并依据此关系由时域奈奎斯特采样定理对应得到了空域采样定理,进而指出ULA阵存在无模糊入射角区间,并推导出了无模糊入射角的计算公式,最后通过仿真验证了结论公式的有效性。
Corresponding relation between frequency response and beam response is analyzed; spatial sampling the- orem corresponding to time-domain Nyquist sampling theorem is obtained based on this correspondence relation. It is indicated that there is unambiguous incident angle interval in ULA array ; and calculation formula of unambiguous incidence angle is deduced. Simulation results verify the effectiveness of the formula.
