Do ships use sonar or radar?

In commercial ships, radars are integrated into a full suite of marine instruments including chartplotters, sonar, two-way marine radio, satellite navigation (GNSS) receivers such as the US Global Positioning System (GPS), and emergency locators (SART).

Can we use sonar instead of radar?

Sonar or so(und) na(vigation) r(anging) works in a manner similar to radar, except sonar uses pulses of sound waves underwater to find the distance to a sound-reflecting target. Also, radar is only an active system allowing for your detection by passive sensors. Whereas sonar can be both passive and active.

Can a submarine ping kill you?

Yes, it can kill you if you are close enough. The U.S. Navy’s sonar emits 235-decibel pressure waves of unbearable pinging and metallic shrieking. At 200 Db, the vibrations can rupture your lungs, and above 210 Db, the lethal noise can bore straight through your brain until it hemorrhages that delicate tissue.
