Abstract: We set up ocean reflection models to study the effects of different ocean surfaces on signal reflec-tions. For a 100 W HF constant carrier signal with a transmission frequency less than MUF, the field strength, after the calm sea surface reflection, is always higher than the field strength after the turbulent sea surface.
