Static Coordinateometry of Nearby Signal Sources Using the Super-Resolution Algorithm MUSIC

This paper describes a software model for solving the static problem of coordinateometry of nearby signal sources using the MUSIC super-resolution algorithm. The mathematical model permits to simulate the reception of a complex L-band radio signal on a flat equidistant antenna array with 4 antenna elements from several sources with different spatial, power and frequency parameters. Implemented MUSIC super-resolution algorithm gives the most accurate results compared to the beam scanning algorithm and the MVDR (Minimum Variance Distortionless Response) super-resolution algorithm. The coordinateometry algorithm, based on the least squares method, allows you to obtain the coordinates of signal sources with an accuracy of dozens of meters. An application with a graphical interface in the MATLAB environment implements the full functionality of the system: from entering initial parameters to visualizing numerical and graphical results. The obtained results can be applied in solving problems of radio communications, radar and radio navigation.
