Effect of an additional sensor on AOA localization performance

This paper investigates the contribution of an additional sensor to the performance of a passive AOA emitter localization system. This problem arises in localization applications where additional sensor resources become available and there is a need to determine where the new sensor should be placed in order to achieve maximum performance improvement. The paper considers optimal placement of an additional sensor and shows that optimal sensor placement is determined by its angular position rather than the emitter range. The results of the paper are illustrated with simulation studies.
