A Computer Based Ionospheric Sounding and HF Noise Measuring System.

Abstract

A system for the automated collection of ionospheric backscatter sounding and HF noise measurement data is described. The system was configured around a PDP 11/40 minicomputer and modified Barry Research FMCW sounding equipment. The real time digital signal processing associated with the backscatter sounder and noise measurement systems is discussed. The data are displayed and recorded in a calibrated mode, and examples are presented. Deficiencies noted in the operation of the system, and plans for the introduction of oblique and vertical incidence sounding conclude the report. (Author)
