Abstract :
A two-dimensional ultrasonic tracking localization system based on DSP is presented in this paper. Adaptive threshold voltage is used to avoid interference in infrared signal of the system. Because digital filter and correlation detection algorithm have been used in the system, the system can track the target accurately in real-time. Experiment shows that the system designed in this paper has the merits of high precision, real-time and good symmetry.
