Abstract

A vehicle-based method to determine the suitability of an object in the vicinity of a vehicle as a suitable positional landmark, comprising the steps of: a) emitting a plurality of radar signals from a vehicle; b) detecting the radar returns from said emitted radar signals reflected by said object; c) analyzing at least one parameter of at least one radar return to determine the extent to which said object is a stationary object; d) analyzing at least one parameter of at least one radar return to determine the extent to which said object is a single scatterer; e) analyzing at least one parameter of a plurality of radar returns to determine the extent to which said parameter varies with the azimuthal angle between said vehicle and said object, f) determining the suitability of said landmark for the results of steps c), d) and e).
