Abstract
An apparatus with ultra wide band (UWB) applications such as radar, position tracking and communications, for example Ground Penetrating Radar (GPR) and Wireless Personal Area Networking (WPANs). An apparatus synchronises a receiver to a received UWB signal having a known hopping code. The apparatus determines a parameter of the signal in a number of time slots; adds the parameter associated with each time slot to a number of corresponding of time and code offset accumulators; and determines the code and time offset accumulator having an accumulated value according to a predetermined accumulator metric as the code and time offset required to synchronise the receiver.
