Doppler Effect in Radar: The apparent frequency of electromagnetic or sound waves depends on the relative radial motion of the source and the observer. If source and observer are moving…
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…
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.…
Multi Channel Data Acquisition System: The Multi Channel Data Acquisition System can be time shared by two or more input sources. Depending on the desired properties of the multiplexed system,…
Principles of Communication Systems: In a broad sense, the term Principles of Communication Systems refers to the sending, receiving and processing of information by electronic means. Communications started with wire…
Fundamentals of Electromagnetic Waves: Fundamentals of Electromagnetic Waves are energy propagated through free space at the velocity of light, which is approximately 300 meters per microsecond. As the object travelled downward,…
Filters in Electronic Instrumentation Articles: What is a Filter Circuit?: A network designed to attenuate certain frequencies but pass others without attenuation is called a filter. A filter circuit thus…
