The present invention relates to a method of detecting and classifying objects using radar. The method means that a broadband radar signal comprising wavelengths that coincide with characteristic lengths of targets to be detected and classified is transmitted. Further, a returned echo signal is received and analysed, at which a signal analysis in a combined time-frequency domain is used, which comprises determining characteristic frequencies in the signal return and their mutual time relations. Finally, a comparison with the corresponding stored values of an analysis of possible targets is performed.
La présente invention concerne un procédé de détection et de classement d'objets au moyen d'un radar. Le procédé décrit la transmission d'un signal de radar à large bande comprenant des longueurs d'ondes qui coincident avec des longueurs caractéristiques de cibles devant être détectées et classées. Il décrit en outre la réception et l'analyse d'un signal de retour d'écho, aux fins desquelles une analyse de signal reçu dans un domaine temps-fréquence combiné est utilisée, ladite analyse consistant à déterminer des fréquences caractéristiques dans un signal de retour et leurs relations mutuelles de temporisation. Enfin, on effectue une comparaison en utilisant les valeurs enregistrées correspondantes d'une analyse de cibles possibles.
