Abstract
Emitter localization, using different types of sensors and integrating their output properly can potentially increase localization accuracy. It is relatively easy to measure the received signal strength (RSS), but RSS localization is generally less accurate than angle-of-arrival (AOA) localization in most practical environments. When both RSS and AOA are available, fusing their measurements can improve localization accuracy. This paper develops a set of linear equations that optimally combines both AOA and RSS measurements, and is suitable for solution by weighted least squares. The simulation results show that at sufficiently low noise, the hybrid scheme is near optimal.
