military radars ppt

Abstract
RADAR (Radio Detection and Ranging) is basically a means of gathering information about distant objects by transmitting electromagnetic waves at them and analyzing the echoes. Radar has been employed on the ground, in air, on the sea and in space. Radar finds a number of applications such as in airport traffic control, military purposes, coastal navigation, meteorology and mapping etc.

The development of the radar technology took place during the World War II in which it was used for detecting the approaching airc ....etc

More Info About active adaptive phassed array radars

a phased array is a group of antennas in which the relative phases of the respective signals feeding the antennas are varied in such a way that the effective radiation pattern of the array is reinforced in a desired direction and suppressed in undesired directions. Phased array transmission was originally developed in 1905 by Nobel Laureate Karl Ferdinand Braun who demonstrated enhanced transmission of radio waves in one direction. During World War II, Nobel Laureate Luis Alvarez us ....etc

INTRODUCTION
The radar systems have been changing on the account of the requirements caused by:- Increase in the number of wanted and unwanted targets. Reduction in target size. Need to adapt a greater no. of electronic counter measures.
CATEGORIES OF RADAR
Two Categories:-
1. Single-function radars.
2. Multi function radar (passive phased array).
SINGLE FUNCTION RADAR
Has fixed antenna with centralized transmitters.
Eg:1) Surveillance radar
2) Tracking radar
MULTI-FUNCTION RADAR
Passive phased array:- use ....etc

ABSTRACT

Adaptive active phased array radars are seen as the vehicle to address the current requirements for true multifunction radars systems. Their ability to adapt to the enviournment and schedule their tasks in real time allows them to operate with performance levels well above those that can be achieved from the conventional radars. Their ability to make effective use of all the available RF power and to minimize RF losses also makes them a good candidate for future very long range radars.

MILITARY RADARS



INTRODUCTION

Military radar should be an early warning, altering along with weapon control functions. It is specially designed to be highly mobile and should be such that it can be deployed within minutes.
Military radar minimizes mutual interference of tasks of both air defenders and friendly air space users. This will result in an increased effectiveness of the combined combat
