Automated people movers are employed or projected in some cities all over the world. To explore the possibility of new exploitation modes, a cooperative correlation based radar collision avoidance system is used to identify trains, detect their positions and compute the distance between them. A problem with such a sensor is that it uses pseudo random codes and that the codes currently employed (m.l.f.s.r.: maximum length feedback shift registers) are few in number, so only one can be used at a time in any place to avoid interference. This study looks for new codes available in a larger number, that deliver good performances in the radar system. Some families of codes used in CDMA or other mobile telecommunication systems have been tested. For these tests a radar detection parameter is defined.
