CHAPTER 1 — BASIC RADAR PRINCIPLES AND GENERAL CHARACTERISTICS INTRODUCTION The word radar is an acronym derived from the phrase RAdio Detection And Ranging and applies to electronic equipment designed for detecting and tracking objects (targets) at considerable distances. The basic principle behind radar is simple - extremely short bursts of radio energy (traveling at the speed of light) are transmitted‚ reflected off a target and then returned as an echo. Radar makes use of a phenomenon

polarization will also occur during reflection‚ refraction‚ and scattering of light. When reflecting off non-metallic surfaces‚ the resulting light will be polarized parallel to the reflected surface. During refraction‚ a beam of light will be split up into two polarized beams‚ one polarized parallel and one perpendicular to the boundary. Scattering also causes partial polarization. Characteristics of Polarization Polarization is a phenomenon peculiar to transverse waves‚ i.e.‚ waves that vibrate

refraction is‚ the formulas used to calculate the refraction measurement‚ etc… Refraction of Visible Light Lerner‚ B. W’s article on Refraction: The bending of light (Citation 1) explains the refraction of white light through glass‚ and how the speed of the light is affected by different media. If light enters a glass at an angle‚ the glass causes the beam of light to slow down and bend at a deeper angle. Furthermore‚ the speed of light increases when it travels from a substance of high density to low

MEN 510 Energy Conversion Assignment 2 Proton Therapy Presented to: Dr. Walid Assaf By: Farid Akiki 20082191 Semester: Fall 2012 Proton Therapy Proton therapy (also called proton beam therapy) is a type of radiation treatment that uses protons rather than x-rays to treat cancer. A proton is a positively charged particle that is part of an atom‚ the basic unit of all chemical elements‚ such as hydrogen or oxygen. At high energy‚ protons can destroy cancer cells.

Machine Design II Prof. K.Gopinath & Prof. M.M.Mayuram FATIGUE CONSIDERATION IN DESIGN OBJECTIVES AND SCOPE In this module we will be discussing on design aspects related to fatigue failure‚ an important mode of failure in engineering components. Fatigue failure results mainly due to variable loading or more precisely due to cyclic variations in the applied loading or induced stresses So starting from the basic concepts of variable (non-static) loading‚ we will be discussing in detail

Function is how the building will be used‚ form is how the building looks‚ and structures is how the building remains standing. Architects need to design structures that hold up under any combination of three physical forces; compression‚ tension‚ and bending. To days architects have a plethora of materials at their disposal‚ they benefit from the evolution of materials and have the opportunity to use them how they wish‚ but it has not always been this way. Primitive buildings were built using dry

The term is used to designate the direction of the x rays in a given projection; the central ray may be considered to extend from the focal spot of the x-ray tube to the film.
