Characterization of a Multisource Angle of Arrival Estimation Technique based on Phase Interferometry

Radiolocation made by using space-spectral function based techniques, like MUSIC algorithm, demonstrated to be very efficient but also greedy of computational resources. In this work we present a behavioral characterization of the Multisource I/Q Low-Pass Mixing (M-IQ LPM) algorithm for multiple incoherent sources AoA estimation, taking into account for most of the well-known artifacts-generator phenomena that impact the position estimation. The analysis is performed through simulation investigating also the influence of the number of sources to identify on the overall estimation quality.
