Team Vision for Detailed Design Phase

During this phase, we planned to get the radar working and talking to the pi, as well as testing how far the radio transmitter/receiver circuit can reach with an antenna, and how sensitive the radar is to objects of different sizes. We also planned on creating housing for the radar, base station, and in-car device, as well as testing the housings in different weather conditions.

We did not get to creating housings yet, as we decided this should be a last step so we know exactly how big the housings should be for each unit. We were, however, able to get the radar working and talking to the pi, as well as complete the testing we wanted to complete.

In the next phase, we plan on integrating the speaker into the in-car device, as well as finalizing the software that will link the radar detection to the radio signal transmission. After this, we will be able to create the housings and do extensive testing, adjusting as needed to test results.
