Radars are getting extremely high tech. This one here will be able to detect a tennis ball some 24 kilometers away, while it's moving at three times the speed of sound no less!

UK's HMS Iron Duke will have the chance to work when it returns to service next year. Developed by BAE Systems for use on the Navy's Type 23 frigates, it is five times more efficient that current technology. Why aren't all warships using this, we wonder.

The radar can track up to 800 things that are moving simultaneously with a range of 200m to 200km.
