A study for high accuracy real-time 3D ultrasonic location system.
We discussed a high accuracy real-time 3D ultrasonic location system in this article. The signal received was sampled after it passed the TGC and the logarithmic amplifier. Inside the DSP, we used the dynamic threshold tracing technique to improve the accuracy. The result was processed with Weighted Arithmetic Average. By testing the 40 kHz 3D location system, we have arrived at the accuracy of 1 cm.
