Summary: A military training film explaining the basic principles behind the function and operation of Radar (Radio Detection and Ranging).
Description: The film explains that Radar is essentially the transmission of a series of single radio pulses at 186,000 miles per second and the reception of the echo bouncing back from a solid object. Measuring and interpreting the returning signal enables the Radar Operators to establish the range, height and bearing of the target, once issues such as 'Clutter', terrain and atmospherics have been accounted for.
Explanations on cathode ray tubes (CRT), the time base, breaks, range, elevation, angle of sight, target speed, scales used on displays, multiple targets, clutter, beam width, pulse strength and length, 'on target in elevation' principles, how reflectors of different shapes affect the results, Planned Position Indicator (PPI) displays and B-Scopes.
Formulas, diagrams, visual illustrations and demonstrations are included, enabling those who are new to the subject to understand the subject.
