Does anyone know what this part/radar is specifically called that handles the adaptive cruise control?

What is your question?

I have a 2011 chrysler 300 c . I need to have the radar replaced that is related to adaptive cruise control/forward collision warning that is located in the front of the car. Near the fog lights (i hit a pole,while parking), however I can not find out the exact name of the part to research it's price. Does anyone know what this part/radar is specifically called?
