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.
