Abstract
This article focuses on the location of radiating sources that are in line of sight, using calculations encompassing wide ranges of an electromagnetic signal. The purpose of using the MUSIC algorithm is to consider the distance at which the transmitting antennas are, implementing a measurement procedure throughout simulations. In order to do these simulations we use a tool that determines the value of the real surroundings electromagnetic field under study and that is validated to provide trustworthy results in a reduced runtime. Thus the signal spatial signature is observed.
The algorithm is based on the UTD (Uniform Theory of Diffraction) and/or ray tracing.
