Radar Guns and Laser radar Guns


This is the age of speed. We can see people zipping down the highways at unimaginable speed. Long before the invention of radar guns in 1970's and laser speed guns in 1990's the police had a very tedious job in detecting those vehicles which where driven at over speed. The radar gun emits microwaves and works on the principle of radar where as the laser gun emits infrared rays and gives more accurate readings than the radar gun. The invention of the radar guns and the laser guns have proved to be a great ble ....etc

Abstract:
Due to the threat of terrorism, today's enemy can be anyone and they can exist anywhere even in populated cities. Monitoring human activities in an urban environment is a difficult problem due walls, clutter, and other obstructions. This seminar discusses the development of a network of digital noise radars that operate simultaneously to track humans and non-human targets inside rooms and through walls. Each individual noise radar works by cross correlating the received signal with a time delayed replica of the transmit signal. A hi ....etc

ABOUT YOUR SONAR
TERMINOLOGY:
The following is an explanation of the basic terms used by Imagenex to describe their sonar
techniques.
Color: The different colors used to represent the varying echo return strengths.
Echo: The reflected sound wave
Echo Return: The time required for the echo to return to the source of the sound
Sonar: The principle used to measure the distance between a source and a reflector (target)
based on the echo return time
Target: The object that you wish to obtain information about.
IMAGING: Fan shaped b ....etc

MIMO RADAR SIGNAL PROCESSING:MIMO as a Distributed Radar System
ABSTRACT:

Multiple-input multiple-output (MIMO) radar has been receiving increasing attention in recent years from researchers, practitioners, and funding agencies. MIMO radar is characterized by using multiple antennas to simultaneously transmit diverse (possibly linearly independent) waveforms and by utilizing multiple antennas to receive the reflected signals. Like MIMO communications, MIMO radar offers a new paradigm for signal processing research. MIMO radar possesses sig ....etc

GRIFO Radar: High-resolution modes for an expert avionic radar for fighters

Vaibhav Prajapati (07BEC131)
Chitrang Shah (07BEC093)



Abstract—

The need for the implementation of high-resolution modes, with seaborne targets identification for the Italian Navy, pushed to the extension of the Grifo Radar to high-resolution applications.With the new capability, making use of the Deramp On Receive technique, Grifo Radar can now perform Spot-SAR on ground patch as well as ISAR upon A/A and A/S tar ....etc

RADAR AND SYNTHETIC APERTURE RADAR BASICS
PRINCIPLES OF RADAR
HOW DOES RADAR WORK?
• RADAR = Radio Detection And Ranging
• Since radar pulses propagate at the speed of light, the difference to the “target” is proportional to the time it takes between the transmit event and reception of the radar echo
PRINCIPLES OF IMAGING RADAR
REAL APERTURE RADAR
• PRINCIPLES OF IMAGING RADAR
THE RADAR EQUATION
• The SNR is derived from the radar equation:

where
Peak ....etc
