UWB-IR is an excellent choice for precision positioning systems because of its inherent advantage in providing very good accuracy while operating dense multipath environments. This paper describes a UWB-IR transceiver that acts as an active reflector for ranging applications. The active reflector works as a ranging or positioning tag that can be attached to objects whose range or position needs to be tracked. The active reflector consists of a Schottky diode receiver and a MOSFET driven Step Recovery Diode pulse generator. The system was designed, built and tested. The measured results verify its suitability for ranging and positioning applications.
