Antenna Tracking System: Having acquired a target through a scanning method as just described, it may then be necessary to locate it very accurately, perhaps in order to bring weapons to bear upon it. Having…
Antenna Scanning Methods: Radar antennas are often made to scan a given area of the surrounding space, but the actual scanning pattern depends on the application. Figure 16-6 shows some typical Antenna Scanning Methods. The…
Pulsed Radar System Block Diagram: A very Pulsed Radar System Block Diagram set was shown in Figure 16-1. A more detailed block diagram will now be given, and it will then be possible to compare…
Radar Performance Factors: Quite apart from being limited by the curvature of the earth, the maximum range of a radar Set depends on a number of other Radar Performance Factors. These can now be discussed,…
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 of sending out a large UHF or microwave…
Routing Code and Signaling System: Routing Code and Signaling System - When dialing a subscriber in another part of the world, it is essential to identify the wanted telephone number uniquely, so that the international…
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 polarities fed from opposite ends…
Applications of Tropospheric Scatter Links: Applications of Tropospheric Scatter Links also known as troposcatter is rather similar to a microwave link terminal, and indeed a typical block diagram is sufficiently like Figure 15-5 that a separate block…
Microwave Link in Electronic Communication: A Microwave Link in Electronic Communication performs the same functions as a copper or optic fiber cable, but in a different manner, by using point-to-point microwave transmission between repeaters. Many…
Coaxial Cable in Communication System: A Coaxial Cable in Communication System consists of a tube carrying a number of coaxial cables of the type, together with repeaters and other ancillary equipment. Separate cables are used…
