An X-band marine radar system was employed in the vicinity of Hazaki Oceanographical Research Station (HORS) located at Ibaraki prefecture of Japan. The nearshore region around HORS exhibited a complicated morphological feature represented by a barred beach as a result of frequent exposure to large storm events. The radar system provides subsequent wave images having a clear variation of wave pattern during a storm event. These images were analyzed with an improved approach based on spectra analysis and PIV technique. Both wave period and spatial distribution of wave celerity vectors were determined based on a refined approach to Bell (1999). A linear bathymetric inversion algorithm was initially examined and then applied to derive the nearshore bathymetry around HORS. The computed beach profile showed an appropriate agreement with the measured ones. However, there is a discrepancy existed due to ignorance of nearshore currents.
