MEASUREMENT OF MAXIMUM TIME-DELAY RESOLUTION OF OBLIQUE SOUNDINGS ON EAST-WEST AND NORTH-SOUTH PATHS

Abstract

The purpose of the investigation was to determine the maximum usable bandwidth of an HF, ionospheric channel, in a system which does not compensate for ionospheric distortion. A high-resolution, oblique 'chirp' FM-CW sounder was used to measure the minimum equivalent pulse widths which could be transmitted over paths having characteristics typical, respectively, of geomagnetically east-west and north-south propagation. The path used to represent east-west propagation was from Lubbock, Texas to Stanford, California. The path used to represent north-south propagation was from Bozeman, Montana to Stanford.
