Résumé / Abstract
Obstacle detection by radar can applys as much to the field of road transport as to those of public transport. This study led to the realization of a dual-mode radar, coupling the advantages of the two systems, but nevertheless expensive. Then, with the help of the doae, we studied a radar sensor using the correlation of pseudo-random binary sequences. This model was initially intended for the road field. A second step consisted in adapting the principle of the correlation radar to the field of public transport of a subway type. Several types of responders will be tested soon in tunnel on the automatic subway network of Lille. This system of correlation radar, combined to simple responders, could also lead to road applications, for the detection of particular fixed obstacles, such as the piles and decks of bridges, or certain road panels, which are difficult to filter on the current autonomous radar systems, because of the significant energy that they return towards the sensor. We will continue our work bearing this point of view in mind.
