Multidimensional scaling algorithm of localization with hybrid TOA and AOA measurements

Recently, multidimensional scaling (MDS) algorithms have been verified to be robust for the emitter localization. However, the traditional MDS algorithms are based on single one kind of measurement. In this paper, a novel hybrid MDS localization algorithm based on both angle-of-arrival (AOA) and time-of-arrival (TOA) measurements is proposed. In the condition that one of the sensors can obtain the AOA of the emitter, this algorithm utilizes AOA measurement to improve the traditional MDS localization based on TOA measurements. The simulation results demonstrated the improvement of this algorithm.
