A method of determining the de-aliased range rate of a target in a horizontal plane by a host vehicle equipped with a radar system, comprising: emitting a radar signal at a single time-point instanceand determining from a plurality of point radar detections measurements therefrom captured from said radar sensor unit, the values for each point detection of, azimuth and range rate; for each point detection determining a range rate compensated value; determining a plurality of velocity profile hypotheses; for each hypothesis determining modified compensated hypothesis range rates in respect of each point detection on the target, based on the values of range rate compensated; for each hypothesis, determining values of the longitudinal and lateral components of the range rate equation of the target for each hypothesis and for each point detection determining a velocity profile estimator range rate for each hypothesis, for one or more point detections, determining a measure of the dispersion of, or variation betwee
