Approximation error in near field source localization using bistatic MIMO
Résumé
The existing near field sources localization techniques are based on an approximated model which brings error with it. In bistatic MIMO system, it takes a combined form due to the two arrays. This error is small but may be significant for a precision demanding application. Therefore, we can either use exact model based method to obtain the directional parameters or correct the directional parameters obtained from the approximated model based methods.
