OPTIMUM FREQUENCY DETECTION TECHNIQUES.

Abstract

This report covers Phase I of the study and investigation of techniques for a high frequency (HF) ionospheric sounding system which is to provide real-time determination of the optimum frequency for use on tactical HF communications circuits. Topics included in the study are (1) ionospheric sounding systems, (2) frequency coverage, (3) transmission energy, (4) radio frequency interference and (5) multipath. A system configuration is recommended utilizing 150 microsec pulses to evaluate circuit conditions by comparing multipath amplitude and time separation with pre-determined values. (Author)
