We have previously proposed the moving source tracking method using MUSIC and PAST, in which the PAST is the algorithm for estimating the signal subspace sequentially.Then, the MUSIC spectrum must be calculated for all the interesting direction, and thus its cost tends to be enormous with a high estimation precision.In this paper, we formulate a moving source tracking problem as the constrained optimization problem and solve the problem using IPLS algorithm to the reduce computational costs.Several experimental results are shown to present a superior performance regarding estimation precision
and computational cost of the proposed method. |
