Abstract: The present disclosure relates to a radar device and technique for detecting the presence of objects located in the near-field of a frequency modulated, continuous wave (FMCW) radar device. The technique includes transmitting and receiving a frequency modulated signal, generating an intermediate frequency signal based on the transmitted and received signals, and analyzing the frequency content of the intermediate frequency signal. The frequency content of the intermediate signal is analyzed without filtering out a carrier signal.

Abstract: “RABBIT RAIL” is a light rail system that uses standard commuter busses which are fitted with railroad wheels that can be lowered, so the bus can run on railroad tracks or raised to run on roads. Present light rail systems require commuters to drive to a rural rail station where they board a railcar. They are then taken into the city station where they must now find other transportation to get to work. “RABBIT RAIL” travels on rural roads to where the commuter lives. The bus then drives to the nearest rail-on/off siding, where it lowers the rail wheels. It then drives on the rails into the city with no stops. In the city, the bus pulls onto another rail-on/off siding and raises the rail wheels. The bus then drives onto the city streets to take the commuters to where they work all on the same “RABBIT RAIL” bus. This is called door to door service and that is what commuters want.
