Automobile Reversing Radar Based on Ultrasonic Wave
Automobile reversing process should be paying more attention for security. This paper analyzes the principle of ultrasonic distance measurement, made simple and practical automobile reversing radar, in which the SPCE061A MCU / DSP of high-performance 16-bit microprocessor was used as the control core and the ultrasonic sensors modular for detection signal. The system design is the modularization structure, so as to simplify the debugging effort, well done eventually reversing radar. The experiments shows that the detection range may be up to 15cm-200cm, the error of distance is only 5cm, fully meet the practical requirements, and low cost.
