Which came first sonar or radar?

Americans began to use the term SONAR for their systems, coined by Frederick Hunt to be the equivalent of RADAR.

How many radars are there in India?
There are currently 27 Doppler radars in the country.
Can radar detect humans?
Doppler radar cannot detect humans who are stationary or walking across the radar’s field of view. The radar can only detect the motion components that are directed towards to or away from the radar. However, if the environment does not contain any strong radar reflectors, the system can also be used when moving.
