Results of the work on remote monitoring of sea surface state in the Taman Bay using X-band incoherent navigation radar FURUNO 1715 in 2009–2011 are presented. The Taman Bay is characterized by a short wave fetch and typical wave heights less than 1 m, when radar spectral methods for restoring the wave height fail to work. Therefore, regarding the cases with wind blowing to the shore, the so-called radio-brightness method was applied and corresponding calibration transmission functions for the wave height retrieval were calculated. Comparison of the radar measurements of wave heights with the wave gauge data has showed their good agreement for the cases of wind blowing to the shore in the sector of angles from –60° to 80°. The correlation coefficient between the radar and in situ data is 0.85, the standard deviation is 0.14 m. Simulations of the wave heights in the Kerch Strait and the Taman Bay provided by the SWAN wind-wave model have confirm the validity and reasonability of applying the radio-brightness method for sensing wind wave height in the conditions of the Taman Bay, and bays with similar conditions.
