The paper describes the implementation of a novel approach to ultrasonic ranging systems based on a modified frequency variations monitoring technique. The whole system is developed on a single-chip FPGA, which serves both roles as generator of the specialized signal and as timing analysis hardware in the receiver module. Details of the different tasks and operations which form the structure of the whole system are also given.
