Radar technology uses radio waves refraction to calculate distance, speed and direction of a body. Miniaturization of radars and decreased costs render them suitable for personal uses, such as heartbeat control, blood pressure check, driving support.

Experts estimate that very soon radar to inform the drivers of possible obstacles in blind spots will become a standard car equipment (now, they are already installed on some top range BMW), and radars may become a good alternative to medical tests based on ultrasounds.

Tests are now being conducted to use smartphones as personal radars, taking into account they already have the three necessary components: a radio transmitter, a receiver, and processing capacity.

Then, personal radars will be soon everywhere.
