RADAR Engineering Basics

RADAR Block Diagram- Types of RADAR (Monostatic RADAR and Bistatic RADAR)- Duplexer in RADAR

This video lecture discusses the block diagram of RADAR. Here two Types of Radar are discussed- Bistatic Radar and Monostatic Radar. This Classification of Radar is based on the number of Radar antenna used. In Bistatic radar two separate Antennas are used for transmission and reception purpose while in case of monostatic Radar only one antenna works as a transmitter and receiver antenna. For this purpose the monostatic radar uses duplexer. This video lecture also discusses the functions of Radar duplexer.

RADAR- RADAR System- RADAR Advantages and Disadvantages- Uses of RADAR and Working- RADAR Full Form

In this video you will understand- what is Radar, the basic working principle of Radar, advantages and disadvantages of radar along with uses of Radar (applications of Radar). You will also know the full form of Radar. Radar is an acronym for radio detection and ranging. Radar uses electromagnetic waves (Radio waves) towards the target and analyses the reflected waves (echo signal) to gather some information about it. This video also compares Radar with Sonar (radar vs sonar). Applications of Radar have been categorized mainly in two parts- Civilian applications and military applications.

RADAR Range Equation - RADAR Equation - Derivation of RADAR Range Equation - Range of RADAR

In this video you will get the derivation of Radar range equation. Here you will understand the basics of Radar range equation. You will find here the radar range formula. Radar range equation relates the range of the radar to the transmitter and receiver of the radar, antenna of the radar and target. It is also related to the medium of the environment. This video explains the concept of power density, Gain and directivity of the antenna. The power received by radar and Radar cross section of target has also been covered. You will find here two forms of Radar range equation.

Desirable Qualities of RADAR System - General Requirements for RADAR System - RADAR Engineering

This video is about the qualities of a good Radar system. Following are the general requirements for a radar system. 1.The transmitter of Radar should be able to transmit high power signals so that it can counter the attenuation that is caused in the forward and backward paths. 2.The Radar transmitter should remain silent during the echo period. 3.The receiver of the radar should be very sensitive as it has to catch very weak echo signals. 4.The transmitted signal by the radar transmitter should be highly directive and it should have high gain since it needs to transmit strong signals to counter attenuation.
