Once the stuff of science fiction, autonomous cars are now reality. To work properly, these self-driving vehicles rely on input from a multi-modular system of sensors, including ultrasound, radar and cameras –and to prevent crashing, they must convert the acquired information and filter it into data needed to control action. Signal processing is integral to the technology. It helps decide whether the car needs to stop or go and is part of the radar used to decipher weather conditions like rain or fog.
