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.…
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…
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…
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…
Telemetry in Electronic Communications: Telemetry in Electronic Communications consists of performing measurements on distant objects. Although hydraulic or wire circuits may be used for this purpose, this section will deal…
Cryogenically Cooled Amplifiers: The term solid-state is used deliberately here; it does not mean "semiconductor." In terms of the somewhat older maser parlance, it means the opposite of gaseous, i.e.,…
Ruby Maser: As was know ferrites of certain materials have atomic systems that can be made to resonate magnetically at frequencies dependent on the atomic structure of the material and…
Parametric Amplifier Types: The basic Parametric Amplifier Types have already been discussed in detail, but several others also exist. They differ from one another in the variable reactance used, the…
