Description
RADAR systems subject is completely dealing with War field communication to transmit and receive signals and types of various radar systems used in communications.
Students able to learn how to receive signals from noisy environment and also able to learn about different types of display units.
Prerequisite
• Better to have the knowledge over communications and microwave components since all the radar block diagrams use microwave communications.
For whom
• This tutorial has been developed for Electronics students to help them understand the basic to advance concepts related to the Radar systems.
• It will also be helpful for those students who are preparing them for their engineering syllabus.
