Scientific paper

Attention is given to the signal-analyzer-and-sampler (SAS) experiment aboard the Active spacecraft, the scientific objective of which was to study whistler/VLF ducted propagation, VLF duct structure, and the hyperfine structure of whistlers. Results concerning the hyperfine structure of the whistlers are presented. Recorded as several pairs of closely spaced traces (doublets), the whistlers are interpreted as ducted whistlers escaping at a high altitude from single or two closely spaced narrow ducts and reaching the satellite directly from above or after reflection from below. The whistler tracers were processed by a sophisticated matched filter technique which allowed very high resolution dynamic spectra to be obtained. The hyperfine structure of traces revealed by this technique demonstrates the complexity of whistler propagation. The observed splitting of traces is explained in terms of a number of guided modes and by the superposition of closely spaced ducting structures.
