Radar and communications are two different applications of radio waves.
For radar, directional antennas are used, and the normal antenna for a ship installation would be a parabolic reflector with a rectangular aperture about 5 times wider than its height. This gives a narrow beam in the horizontal direction, and pulses are sent out and detected after being reflected by the target.

What is a weather radar?
A weather radar is a type of radar used to locate precipitation, calculate its motion, estimate its type (rain, snow, hail, etc.), and forecast its future position and intensity.
What is the Radar used to eliminate clutter in navigational application?
tracking radar
Who made the radar?
As far as I know, radar was invented by a Hungarian scientist named Zoltan Bay. That radar was first used in World War II by the British troops.
What is the radar for?
Radar is used to detect concentrations of water droplets in the atmosphere, which tells meteorologists where rainfall, snow and hail are occurring.
Which type of communication systems are used nowadays?
Like Facebook,texting,twitter,and other social media sites.
What type of antenna is used for satellite communication?
parabolic
What is The size of antenna used in the satellite systems?
Light weighted antennas are used for communication
What is ground penetrating radar used for?
Ground penetrating radar (GPR) is a geophysical method that uses radar pulses to image the subsurface. When the waves hit an object, the receiving antenna can be used to distinguish what it is. This can be used to find precious metals, like gold, underground.
What radar do?
At the minimum, a radar is a device that can detect the range of the target object (ie. radar gun used by law enforcement). A more advanced radar can locate the range and direction of the target object (via the azimuth). For example, the old spinning radar antenna seen on TV can locate an object based on the detected range and the direction the antenna is facing at the time. These can still be used to track the weather as clouds can be tracked. The most highly advanced radar can identify just about everything about the target object as if it is in front of you. An example of use is tracking space junk.
What is the meaning of Radar?
Radar systems usually use wavelengths and are associated with digital signal processing. They consist of a transmitter, antenna receiver, switch, data recorder, processor, and display. Radar systems are used to track things including weather.
