Le radar à impulsions UWB (ultra large bande) est un candidat prometteur pour les systèmes de surveillance. L'algorithme d'imagerie rapide SEABED (Shape Estimation Algorithm based on BST et Extraction of Directly scatterwaves) est déployé dans l'application du radar à impulsions UWB dans des domaines nécessitant des opérations en temps réel. Cependant, étant donné que l'algorithme SEABED utilise des signaux reçus à plusieurs endroits, cette méthode nécessite soit de scanner des antennes, soit d'installer de nombreuses antennes. De tels systèmes sont inévitablement coûteux et irréalistes pour des applications telles que la surveillance. Pour surmonter ce problème, un algorithme SEABED révisé qui estime la forme inconnue d'une cible sur la base du mouvement de la cible en utilisant uniquement une paire d'antennes fixes a été développé. Cependant, la méthode ne peut pas être utilisée lorsque la cible se déplace arbitrairement car elle suppose que le mouvement de la cible est parallèle à la ligne de base de la paire d'antennes. Dans cet article, nous proposons un nouvel algorithme d’imagerie radar UWB applicable même aux cibles ayant un mouvement arbitraire. La méthode proposée introduit une autre antenne qui est ajoutée à la paire d'antennes utilisées dans le fond marin révisé et estime le mouvement d'une cible inconnue en fonction de la surface cible à l'aide des trois antennes. Ensuite, la méthode proposée applique l’algorithme d’imagerie SEABED au mouvement estimé et obtient l’image cible. Certaines simulations numériques établissent que la méthode proposée peut estimer avec précision la forme de la cible même dans des conditions sévères.

Abstract: UWB (ultra wide-band) pulse radar is a promising candidate for surveillance systems. The fast SEABED (Shape Estimation Algorithm based on BST and Extraction of Directly scattered waves) imaging algorithm is deployed in the application of UWB pulse radar in fields that require real-time operations. However, since the SEABED algorithm uses signals received at multiple locations, this method either needs to scan antennas or to install many antennas. Such systems are inevitably costly and unrealistic for applications such as surveillance. To overcome this problem, a revised SEABED algorithm that estimates unknown target shape based on target motion using only a pair of fixed antennas was developed. However, the method cannot be used when the target moves arbitrarily because it assumes the target motion is parallel to the baseline of the pair of antennas. In this paper, we propose a new UWB radar imaging algorithm that is applicable even for targets with arbitrary motion. The proposed method introduces another antenna which is added to the pair of antennas used in the revised SEABED, and estimates unknown target motion based on the target surface using the three antennas. Next, the proposed method applies the SEABED imaging algorithm to the estimated motion and obtains the target image. Some numerical simulations establishes that the proposed method can accurately estimate the target shape even under severe conditions.
