Abstract
Disclosed are a method and a device for the removal of ambiguity in distance. The method computes the distance of the targets detected by the radar using several estimation functions (21, 22, 23). When the estimation functions give substantially the same result, the targets are defined as being in the field of non-ambiguous distances and when the estimation functions give different results, the targets are defined as being in the domain of ambiguous distances. Application especially to frequency-shift keying, continuous-wave radar for automobile traffic control.
