This week and the last week during carnival Vrishab and I worked on collecting a lot of data from our antenna configuration in order to see if the two antennas we had were properly synced and picking up proper signals. We found out that in our test environment in the ECE lab there were WiFi signals on our channel that were interfering with our calculations and so we were able to remove them from the network when testing which fixed all of our issues. After removing these devices we found that our signals were synced properly and correlation worked well and we could achieve and angle of arrival from the data. From here we integrated two more antennas for the full 4 antenna design which was a very smooth transition. Upon adding the new antennas all we had to do was account for N=4 antennas in our code rather than N=2 and everything worked perfectly.
We then spent time collecting data with 4 antennas and performing beamforming with two devices in the room and calculating the angle of arrival from these devices which worked for us. During this time of testing Txanton was able to send up the heatmap overlay code which we were able integrate into the system with our webcam fairly easily.
The objective for next week will be to integrate the webcam such that it interfaces with our angle of arrival data since currently all we interfaced currently is dummy data onto the webcam input. We will also take measurements to figure out our resolution to see if it matches our initial goals.
