**6.5 Side obstacle detection**

This system addresses a side looking short-range radar that operates at 24 GHz. This sensor identifies and detects side obstacles that are signaled with a proper display. As a further option, the system can also be linked to engine control with a view to controlling speed. This function is called "Smart Cruise". More recently, the side obstacle detection System has been introduced also on Volvo cars based on camera sensor and image processing.
