A SPECTRUM ANALYZER FOR ATMOSPHERIC 'WHISTLER' STUDIES
Abstract
A new spectrum analysis system designed around an analyzer operating on a frequency-scan prin-ciple is described. The new system is considerably faster than time-scan equipment, being capable of producing comparable spectrum graphs, of good resolution, in only four times original data time. A faster data rate, up to and including real-time, may be obtained with corresponding loss in resolution. An historical background is included, first mentioning earlier whistler studies and then outlining events in the Ballistic Research Laboratories whistler study program which led to the requirement for a faster spectrum analysis system. A detailed description is given of the design and operation of the new spectrum analysis system and sample spectrum graphs made on both the old and the new equipment are reproduced for comparison.
