Foreword This Technical Report (TR) has been produced by ETSI Technical Committee Electromagnetic compatibility and Radio spectrum Matters (ERM). The present document includes necessary information to support the co-operation under

19、 the MoU between ETSI and the Electronic Communications Committee (ECC) of the European Conference of Postal and Telecommunications Administrations (CEPT). Executive summary The present document describes the radar based surveillance applications in the 76 GHz to 77 GHz for non-automotive ground bas

20、ed vehicular / mobile applications which in most cases are safety related. A high number of accidents in the public transportation area (trains and trams) or with construction/off road vehicles need an increase in the safety in these areas. Information on accidents is described in annex A. The 76 GH

21、z radar technology as realized in EN 301 091 i.1 is also suitable for applications in rail, maritime, construction, agriculture, leisure vehicles, unmanned vehicles and ground transportation. The automotive radars provide safety features and have reached a high penetration. The penetration will furt

22、her increase significantly with the introduction of radars not only in higher but also in lower class cars. The coexistence for all mobile ground based vehicular applications in the 76 GHz to 77 GHz can be based on the mitigation / sharing mechanisms between automotive radars. Such automotive mitiga

23、tion techniques are studied in a European funded project, called MOSARIM www.mosarim.eu. The results of the project and the automotive industries implementation of mitigation / sharing techniques for their systems will be reflected in an future update of the related ETSI standards, like EN 301 091 i
