Summary:Anomalous propagation of microwave and millimetric radiation in the surface boundary layer makes assessment of radio wave systems difficult and subject to significant error due the variability of meteorological parameters. The validation of models relies on trials that involve ships moving with sensors recording meteorological parameters, on paths where coordinating radio link and radar experiments are operating. The Tropical Air-Sea Propagation Study (TAPS) held near Lucinda North Queensland was such a study. This paper presents an analysis of microwave and millimetric wave (9, 17 and 35 GHz) transmit-receive link measurements recorded during TAPS for the period when BPSK modulated waveforms were being transmitted to ranges well beyond the radar horizon. The radio wave propagation measurements described are used to investigate the suitability of using Fourier-Split-Step 2-D parabolic equation methods for modelling microwave and millimetric propagation in sea surface environments. The limitations of these methods used for predicting wave propagation are demonstrated.
