wires between the sender and receiver. Radio‚ on the other hand‚ requires no such physical connection. It relies on the radiation of energy from a transmitting antenna in the form of radio waves. These radio waves‚ traveling at the speed of light (300‚000 km/sec; 186‚000 mi/sec)‚ carry the information. When the waves arrive at a receiving antenna‚ a small electrical voltage is produced. After this voltage has been suitably amplified‚ the original information contained in the radio waves is retrieved

modulated. Pulse-modulated radar can determine the distance to a target by measuring the time required for an extremely short burst of radio-frequency (r-f) energy to travel to the target and return to its source as a reflected echo. Directional antennas are used for transmitting the pulse and receiving the reflected echo‚ thereby allowing determination of the direction or bearing of the target echo. Once time and bearing are measured‚ these targets or echoes are calculated and displayed on the

The book shows Margie‚ that has never had contact with a TV satellite antenna hearing one of her friends tell her that Fariborz‚ a close friend‚ which had just won that kind of antenna with international channels. Excited she jumps into a car and drives to her friend’s house where she watches MTV and EUROSPORT. She says‚ “We could finally experience a view different from the

Discuss how changing the type of antennas affects the amount of signal spilling outside the building? What are your recommendations? In this situation if the campus is using Omni-directional antennas and we are getting a significant amount of spillage‚ it is a problem that could be related to using Omni-directional antennas. With the antenna signal spilling out much farther than it needs to go in any given direction. It could be a situation where directional antennas in certain spots may have created

weapons delivery. Radar Servo Tracking System One of the most basic tracking system designs is the servo tracking system. Here‚ the radar antenna is initially directed on a target after which it automatically remains pointed at the target as it follows its motion. Furthermore‚ the system provides continuous position information to the operator. The antenna is rotated by a motor which provides a negative position feedback signal to a controller. This subsystem is known as a servo-mechanism. Fig

GOOGLE BALLOON ABSTRACT: Many of us think of the Internet as a global community. But two-thirds of the world’s population does not yet have Internet access. Project Loon is a network of balloons traveling on the edge of space‚ designed to connect people in rural and remote areas‚ help fill coverage gaps‚ and bring people back online after disasters. In an effort to provide affordable Internet access in areas with little or no infrastructure‚ Google has begun lofting wireless Internet

with the use of radar‚ planes can use antennas to detect other enemy airplanes‚ they might also have them in modern day airports to help the pilot find the landing strip while in the air‚ the radar will send transmitted information to the pilot that will help them prepare to land. It’s not only used for these practices though it can also be used for many modern day 21 century objects in your home as well such as the microwave oven‚ the television‚ antennas and transmitters and the satellite radio
