This is an overview of the main function.

The main part is a digital signal processor, which creates the ultrasonic burst. The Signal is send out by the transmitter, reflected by an object and received by the sensor array.

I will focus on 2D scanning at first. Therefore the sensor array only consists of two sensors, aligned in a row with the transmitter. This also simplifies the required calculations for object detection.

In this first prototype sensor 1 and 2 are 160mm apart, the transmitter is located in the middle between the sensors.
