An apparatus and method obtains positional information about one or more objects in a detection field. An array includes a transmitting element and a plurality of receiving elements. A truncated cross-correlation function may be applied to determine the interval between signals received by a plurality of the receiving elements, thereby to determine an angular position of an object. A warning zone may be defined and it is determined whether an object is within the warning zone. Also disclosed are techniques for stretching received signals, and techniques for obtaining positional information relating to an object using non-Doppler radar.

Methods and apparatus for obtaining positional information

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.

Electromagnetic sensor system

Apparatus for determining positional information for an object transmits a probe signal towards the object. The probe signal as returned by the object is received at a plurality of spaced apart locations. The relative timing of the returned probe signals as received at the plurality of locations is detected, whereby positional information for the object can be determined. A number of realizations of the invention are disclosed.
