Characterization of wall parameters and autofocusing techniques for through - the-wall-imaging system

Abstract

In this paper an experiment has been done on proposed algorithm for calculation of wall parameters. 2D-beam forming image has been developed by using calculated wall parameters, but calculated wall parameters are not so exact so auto focusing techniques based on higher order statistics has been presented that correct wall ambiguities. All data has been taken in real time environments by interfacing the VNA to the laptop.
