What are the 3 major components of radar?

A radar system consists of a transmitter producing electromagnetic waves in the radio or microwaves domain, a transmitting antenna, a receiving antenna (often the same antenna is used for transmitting and receiving) and a receiver and processor to determine properties of the object(s).

Modern radars not only detect target and measure distances, but they also have the capability of locating, imaging, and identifying targets. A typical radar consists of a transmitter, an antenna, a receiver, a signal processor, and a display . There are different types of radars.

It consists of six components: (1) array antenna front end, (2) T/R modules, (3) array antenna backplane, (4) radar back end, (5) radar processor and display, and (6) radar scheduler.

The marine radar works on the basic principle of electromagnetic waves . The radar antenna sends the high-speed electromagnetic waves to establish the location, which is the distance, the velocity and the direction the wave travelled along with the altitude of the object, moving or stationary.
