In this paper, we have applied SEABED algorithm to experimental data. The random components in the received signal degrade the estimated image. Two kinds of smoothing method to solve this problem have been investigated. One of them directly utilizes the 2nd order derivative, which cannot improve the image accuracy. The proposed smoothing method utilizes the upper bound of the 2nd order derivative instead of the 2nd order derivative itself. The proposed smoothing method has been confirmed to significantly improve the image, which corresponds to the gain of 5 dB in S/N. In the future study, it is important to extend the proposed smoothing method in order to get rid of the required condition of target shape
