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

Seminar on Active Microwave Radar


What can we measure?

Satellite height
Significant wave height
Wind Speed

Aliasing

The altimeter measures sea level once every repeat period (except at cross-over points)
If we have a high frequency signal which we measure at a low frequency we get aliasing
Because of the way the altimeter lays down its tracks these aliased signals appear to move ....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.

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

Abstract

We investigate whether, and to what extent, the physical phenomenon of long-lifetime resonant electromagnetic states with localized slowly-evanescent field patterns can be used to transfer energy efficiently over non-negligible distances, even in the presence of extraneous environmental objects. Via detailed theoretical and numerical analyses of typical real-world model-situations and realistic material parameters, we establish that such a non-radiative scheme can lead to strong coupling between two medium-range distant suc ....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

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 targ ....etc

Introduction

Speed radar and laser guns are primarily used in law enforcement to detect the speed of a passing vehicle. With the introduction of video recording systems in police vehicles it has been natural requirement to interface the speed gun with the video system. This will produce an indisputable video recording of the actual vehicle along with the speed of the vehicle overlayed in the video
simultaneously. Review in court or reviewed at the scene, lends itself to higher prosecution rates therefore high revenues ....etc
