The issue of the modal rebalance has concentrated the attention of European countries on the standardization of the railway system in order to allow convoys to travel more simply around all of Europe. It has been reached as a result of the creation of international work groups, the realization of ERTMS/ETCS System (European Railway Traffic Management System/European Traffic control System) and of the relative technical specifications of interoperability. The possibility of applying radar based technologies to ERTMS has been estimated for technologies able to improve the visibility of objects on the track and to bypass the geometric distortion problem in the most complete possible way. Moreover, the radar based technology concurs, if compared to the optical based devices that use cameras, to exceed the problems concerned in the reduction of visibility for atmospheric causes. The objective of the study program is to estimate the possibility to apply, in particular to the High Speed system characterized by a high speed rank and by a line architecture that is quite simple and linear, resorting to a simulation instrument which will concur, opportunely shaped with different scenes, to estimate if it could also be applied to different regimes of circulation. Keywords: ERTMS, ETCS, radar, on sight, accident, railway network, safety, technology, trackside subsystem, trainborne subsystem.
