Abstract
A vehicle ( ) such as a motor road vehicle is fitted with an electromagnetic sensor system comprising transmitting means (e.g. ) for transmitting a radio frequency signal, receiving means (e.g. ) for receiving reflections of said signal from remote objects, sampling means ( ) operable to sample the received reflected signal (or a signal derived therefrom), and processing means (e.g. ) for processing the sampled signal, and operable to detect said reflections in the sampled signal, and to determine information on the presence, position and/or range of said object. The system includes filter means (e.g. ) for preventing radio signals transmitted by other sources or noise spikes from causing interference which results in spurious detections or indications of range by the processing means.
