“Interfacing an Infineon Distance2Go radar sensor with a cybt-213043-mesh Bluetooth LE device to create a radar obstacle detection system.
In this application we interface an Infineon Distance2Go board with a cybt-213043-mesh Bluetooth LE device to create a radar obstacle detection sensor mounted in the front of a car. The measurements are sent via Bluetooth to a modified version of CySmart App on a smartphone.The complete setup is powered via a USB power bank.
Infineon-Radar FAQ PDF provides an overview of the different modes of operation of the Distance2Go board, giving insights into the theory of radar speed and distance detection. During this project, we will be using FMCW-mode to measure distance (for an in-depth description see page 4 of the document).Summarized, in this mode the Distance2Go board sends a signal with continously changing frequency and receives the incoming signal bounced off of an obstacle. By mixing these two signals together, the distance to the obstacle can be calculated.
The Distance2Go board is used to periodically measure the distance to the nearest obstacle in front of the sensor.”
