1. A method of detecting an object, comprising the steps of:

  • transmitting a first ultra-wideband (UWB) signal;

    receiving the first UWB signal;

    generating a first waveform that indicates a multipath structure of a propagation channel of the transmitted first UWB signal;

    transmitting a second UWB signal;

    receiving the second UWB signal;

    generating a second waveform that indicates a multipath structure of a propagation channel of the transmitted second UWB signal; and

    comparing the first waveform and the second waveform to detect said object.
