摘要

提出了一种基于相控阵时间序列数据的二维快速傅里叶变换(FFT)的射频信号检测算法。根据两帧信号检测准则计算灵敏度。采用一种由线性相控阵和多个宽带数字接收机组成的采集系统。基于信道化频率方案的系统参数，包括频率范围、本振、混频器和采样频率，给出了仿真结果。对实验到达角数据进行了处理，结果与仿真结果吻合较好。

Angle of arrival measurement using wideband linear phased array

A radio frequency (RF) signal detection algorithm is developed based on two- dimensional Fast Fourier Transform (FFT) on phased array time series data. The sensitivity is calculated based on two-frame signal detection criterion. A collection system consisting of a linear phased array and multiple wideband digital receivers is utilized. Simulation results are presented based on the system parameters of the channelization frequency plan including the frequency range, LO, mixer, and sampling frequency. Experimental angle of arrival data are processed, and the results are shown to be in good agreement with the simulation results.
