We propose and analyze a novel single channel direction finding (DF) algorithm based on phase-locked loops (PLL). The algorithm is evaluated via Matlab simulation to determine the accuracy of the estimated angle-of-arrival (AOA) of a target signal in an AWGN channel. The proposed algorithm is shown to provide exceptional accuracy. Additionally, we present results from a hardware implementation using a software radio platform and an eight-element circular array; they validate the simulation results.
