What system locates an object with radio waves and measures the time taken for the waves to bounce back.?

The system that locates an object using radio waves and measures the time taken for the waves to bounce back is called radar (Radio Detection and Ranging). It emits radio waves that travel to the object and reflect back to the source, allowing the system to calculate the distance based on the time delay. This technology is widely used in various applications, including aviation, meteorology, and traffic monitoring.
