What is a gulf?

A cut into the surface or edge of a coastal area is called a gulf. A gulf is similar to a bay, an area that curves inwards towards land. But it generally occupies a larger area.

Most existing gulfs were formed or greatly extended as a result of the rise in sea level long, long ago with the melting of the glacial ice mass.

Some gulfs have been created as a result of changes in the Earth's crust which caused large areas of shoreline to drop below sea level. The Gulf of California and the Gulf of Oman are examples of this method.

What is radar?

Radar is an electromagnetic sensor used for detecting, locating, tracking and identifying objects of various kinds at considerable distances. The word radar comes from 'radio detecting and ranging'.

It operates by transmitting electromagnetic energy towards objects, commonly referred to as targets and observing the echoes returned from them. The targets may be aircraft, ships, spacecraft, motor vehicles or even birds, insects and raindrops. Radar can not only determine the presence, location and velocity of such objects but also can sometimes obtain their size and shape as well.
