In light of the extant problems of auto video- and ultrasonic radar, we employ the high-capacity, low-power and low-price FPGA chip, which is based on the SOPC technology and optimizes the hard-and software system structure. We also propose a design scheme of the high-accuracy ranging video radar. It is verified by experiment results that the designed system can boost the accuracy of ultrasonic ranging, reduce the cost of video radar, and lessen both the volume and power consumption efficiently. Hence the designed system is of viability and practicality.
