Fiber Optic Communication Articles: Fiber Optics History: In 1870 John Tyndall, a natural philosopher living in England, demonstrated one of the first guided light systems to the Royal Society. His…
Installation of Fiber Optic Cable: Because of their light weight and flexibility, fiber cables are in most cases easier to install than their copper counterparts. There are some concerns, however,…
Fiber Optic Components and Systems: The Fiber Optic Components and Systems can be divided into subgroups, the source, the link, and the detectors. We will now explore the makeup and…
CW Doppler Radar Block Diagram: A simple CW Doppler Radar Block Diagram, such as the one shown in Figure 16-14, sends out continuous sine waves rather than pulses. It uses…
Radar Systems Articles: Basic Radar System Block Diagram: Basic Radar System Block Diagram consists of a transmitter and a receiver, each connected to a directional antenna. The transmitter is capable…
Phased Array Radars: Phased Array Radars - Introduction With some notable exceptions, the vast majority of radars have to cover an area in searching and/or tracking, rather than always being…
Frequency Modulated Continuous Wave Radar: The greatest limitation of Doppler radar, i.e., its inability to measure range, may be overcome if the transmitted carrier is Frequency Modulated Continuous Wave Radar.…
Submarine Cables: Submarine cables use principles very much like those of coaxial cables. Thus they are coaxial, have repeaters and equalizers and have dc power fed to them, with opposite…
