Abstract
A new sensor array based on the EMFi material is presented in this work to perform 3D localization of reflectors. This operation is accomplished by means of an algorithm that performs spherical trilateration using the Time-Of-Flight (TOF) of the emissions from every sensor. An accurate measurement of these TOFs is obtained by encoding the emissions with Kasami binary sequences and applying pulse compression to detect the corresponding echoes. Experimental results show a high level of agreement with the behavior of the simulated model.
