A new Reduced-Dimension MUSIC (RD-MUSIC) algorithm significantly lowers computational complexity for 3D source localization. This method achieves performance comparable to existing algorithms while being more efficient for practical applications.

Area of Science:

Signal Processing
Array Signal Processing
Electromagnetics

Background:

Accurate three-dimensional (3-D) source localization requires elevation angle, azimuth angle, and range.
Classical 3-D Multiple Signal Classification (3D-MUSIC) methods suffer from high computational complexity.

Purpose of the Study:

To propose a novel low-complexity Reduced-Dimension MUSIC (RD-MUSIC) algorithm.
To reduce the computational burden of 3-D source localization using spherical wave-fronts.

Main Methods:

Developed a RD-MUSIC algorithm utilizing a sparse symmetric cross array (SSCA).
Converted the 3-D exhaustive search into three one-dimensional (1-D) searches for angles and range.
Employed a two-stage reduced-dimension method for angle estimation.

Keywords:

DOA estimation reduced-dimension MUSIC (RD-MUSIC)sparse symmetric cross array three-dimensional (3-D) source localization
