 The Design of Reverse the Car Radar of Ultrasonic Wave
   Abstract: The thesis introduces a kind of machine which takes use of a single slice machine technique to carry out electric circuit of reverse the car measure of the radar system to be apart from to carry out principle,the system uses the ultrasonic wave to realized distance measurement without contact. Furthermore,the thesis briefs the functions and features of SPCE061A single-chip microcomputer. analyze with 61 machines for the lord control unit of system hardware and software design, and reversed the car develop of the radar system to carry on through study and research towards measuring to be apart from according to ultrasonic wave of. That system is divided into measure to be apart from mold piece, the system control mold piece and manifestation mold piece. the end to that system carried on to experiment with error margin analytical, make us have further understanding to various function of system.Experiment a result a manifestation, that system has higher accuracy to the distance diagraph of distance, it the main technique index sign come to an a system design a request.
