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

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
MEMS varactors are one of the important passive MEMS devices. Their applica- tions include use in VCOs, tunable impedance matching networks, tunable ¯lters, phase shifters, and true time delay lines. The shunt capacitive structure has been employed in most of the conventional MEMS varactor designs because of its simplicity. However, the capacitance ratio of this conventional shunt capacitive MEMS varactor is limited to 1.5 because of the MEMS Pull- In e®ect, which happens when the de°ection between the MEMS top and bottom m ....etc

Abstract”
Computer supported collaborative applications on overlay networks are gaining popularity among users who are geographically dispersed. Examples of these kinds of applications include video-conferencing, distributed database replication, and online games. This type of application requires a multicasting subnetwork, using which messages should arrive at the destinations within a specified delay bound. These applications also require that destinations receive the message from the source at approximately the same time. The problem ....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

Multicast Routing with Delay and Delay Variation Constraints for Collaborative Applications on Overlay Networks

Maximum variation in the delays from a source to the destinations. The time-complexity of our Algorithm is O (|E| +nk log (|E|/n) +m2 k), where n and |E| are the number of nodes and edges in the network, respectively, k is the Number of shortest paths determined, and Abstract”Computer supported collaborative applications on overlay networks are gaining popularity among users who are geographically dispers ....etc

MSK Direct Sequence Spread Spectrum System Incorporating SAW Tapped Delay Line and SAW Shaping Filter
Abstract
The present work deals with theIF section of an indoor wireless TDMA/CDMA(TCDMA) communication system operating inthe 2.45 GHz ISM band . Spreading anddespreading is done at the 361 MHz IF withan extremely wide bandwidth of 65 MHz whichis greater than the coherence bandwidth of theUHF indoor radio channel. For the modulationof the data we employ on o_ keying (OOK), andfor the spreading minimum shift keying (MSK).Two ty ....etc
