Long range detection using a PDR sensor combined with MIMO antenna

The Pulse-Doppler radar (PDR) is a radar system capable of not only detecting the location of a fixed object, but also measuring its radial velocity by using the Doppler Effect. Taking these abilities, in this paper, we introduce a new PDR sensor which is combined with a Multiple-Input-and-Multiple-Output (MIMO) antenna system in order to enhance the detection range up to 120m. In the experiments at Kookmin University, the proposed sensor performed well to detect moving car at distance 130m - further than we had expected.
