Diversity-Based Geometry Optimization in MIMO Passive Coherent Location

Abstract

Applying the recently emerged technique‎, ‎MIMO (Multiple Input Multiple Output) to PCL (Passive Coherent‎ ‎Location) is expected to improve performance of localization schemes‎. ‎In this paper‎, ‎we explore the‎ ‎application of MIMO technology to PCL schemes and see how it improves the spatial diversity of such systems‎. ‎Specifically‎, ‎we use the DVB-T stations as the‎ ‎illuminators of opportunity in the simulations‎, ‎mainly because of their unique features which‎ ‎make them quite suitable for both MIMO and PCL application as will be demonstrated in this‎ ‎paper‎. ‎In addition‎, ‎we address the key problem of finding optimum locations for placement of receive antennas‎.
