A Localization Method based on the Helmholtz Reciprocity Theorem

Abstract

A localization method for a non-cooperative transmitter based on the Helmholtz Reciprocity Theorem is presented here. The localization method necessitates a propagation model capable of predicting large-scale fading accurately. To this end we use a computational electromagnetics-based approach [1]. Our localization method offers inherent advantages over current methods such as being inexpensive to implement and no necessity for synchronization. The method is implemented here for an undulating rural/suburban terrain profile of 8Km in length. The transmitter is located to within 13.7m with a computation time of 89sec using a desktop.
