An investigation of signal amplitude and wave polarization measurements of radio waves in the 2-32 MHz range over the surface of the ocean is made for short and intermediate range paths, i.e., 0-200 km and 200-1000 km, respectively. The purpose of this investigation is to determine the conditions for which the observed measurements of signal amplitude andor wave polarization at point R are sufficient to determine the range to the transmitter at point T. That is, find RT when 0 RTor200 or when 200 RTor1000. It is shown that sufficient, but not necessary, conditions can be specified for cases where radio range location is possible by making either amplitude or polarization measurements of the RF signal in space andor time.
