An ARMA modeling approach to multitarget tracking

A new approach is presented for locating multiple targets from signals received by a number of spatially distributed sensors. A multi-input multi-output model is assumed to generate the observed data. It is shown that the model parameters are related to the locations of the targets and to their spectra. The structure of the model is explored and a specific algorithm is given for estimating its parameters from sensor measurements. The main feature of the proposed approach is that it estimates simultaneously the parameters of all the targets of interest.
