The detector's output SNR as a criterion for receiver placement in MIMO DVB-T based passive coherent location

Abstract

As the DVB-T (Digital Video Broadcasting - Terrestrial)'s use is outspreading, one of its interesting emerging applications is to use DVB-T stations as non-cooperative transmitters in order to detect and localize targets. An important and favorable characteristic of DVB-T for this application is its being working in a Single Frequency Network (SFN), so that multiple transmitters can be used simultaneously to detect the targets. In addition, using multiple antennas at the receiver side leads to the well known configuration known as MIMO. However, one of the obstacles, arisen in such configurations, is the receive antennas' placement in proper positions so that the detection performance is improved. Here, we propose a criterion based on the designed detector, in order to optimize the geometry of the receivers.
