Currently I am working with TI evaluation boards DAC80504EVM and ADS8920BEVM-PDK. I would like to connect them to ultrasound sensors so that I perform real time generation and processing of ultrasound signals. The final aim of the system is to do 3D ultrasonic distance measurement. Therefore, I would like to generate 5ms long pulses of 100kHz tones from three channels of DAC that are driving three transducers and then receive it with the fourth one that is connected to ADC board. For distance measurement I would need to measure time of arrival between transmission and reception. On the processing side there should be low pass filtering, demodulation, matched filtering and interpolation. Both of these boards can be interfaced to PC via USB cable and come with GUIs that are basically .vi files. I was wondering if I find the way to log the data from these devices directly to Labview, would it be feasible to import Matlab processing scripts and implement the system this way considering the amount of data? Any thoughts?
