Millimeter-wave radars for the railway industry
Until a few years ago, millimeter-wave devices were used almost exclusively in space observation and security applications such as personnel screening and non-destructive testing. Complex and expensive measuring instruments were used in both cases. However, in recent years, these devices have undergone huge technological advances, mainly motivated by the development of radar sensors for automotive applications. This advance has allowed the development of simpler, more compact and more economical sensors which have opened up a new world of applications....
