Estimating the Angle of Arrival from Multiple RF Sources using Phase Interferometry

Currently, many scientists work on localization issues, especially in telecommunication applications. Radiolocation can be performed by means of techniques based on spatial spectral functions, such as the MUSIC algorithm, which have proven to be very efficient but are a significant burden for computational resources. In this work, we present a behavioral characterization of the Multi-Source I/Q Low-Pass Mixing (M-IQ LPM) algorithm for AoA estimation from multiple incoherent sources, evaluating its performance when varying the number of sources.
