  The conventional readout method of the RPC detector uses two sets of
orthogonal readout strips placed at the both sides of the gas gap to collect
signals of opposite polarities to obtain space points. A new readout method
utilizing the reflected signals is proposed which only requires one set of
readout strips. The reflection readout method utilizes the differences in the
arrival time of the direct and reflected signals to determine the hit position.
Customized transmission cables are introduced to extend the propagation
distance of reflected signals to ensure sufficient separation of the two
signals. Because only one side of the readout panel is connected to the FEE
boards, reflection readout method can increase the geometrical acceptance and
save the readout channels. Experimental setup and test results of this novel
readout method is shown in this paper. It is demonstrated that a spatial
resolution of sub centimeter can be achieved by processing the rising edges of
the original and reflected pulses with commonly used electronics.
