Three sets of incident wave conditions were tested: monochro- matic, bichromatic and irregular waves. The paper presents results from the latter two sets. Regarding bichromatic waves, three sets were considered corresponding to difference frequencies of 0.5 rad / s, 1.5 rad / s and 4 rad / s. Table 2 shows the periods and amplitudes of the composing harmonics. The model was also subjected to two long crested irregular seastates, following a JONSWAP target spec- trum with 1.55 s peak period ( Tp ) and peak enhancement factor of 1. In the first case, the significant wave height ( Hs ) was chosen as 6.4 cm, and in the second case 9.4 cm. Calibration runs were performed in order to record the wave patterns without the body scattered waves (runs without the model in place).
