Abstract. Ocean currents are of interest to all who deal with marine affairs. Since they can be predicted, as a result, they are essential as renewable energy for us. We can use it in many applications like navigation, generating electricity, and port constructions. So, studying them and discovering the factors that create and influence them is significant. Using the instrumentation that we can use continuously and do not have many problems is preferred. Therefore, using new technologies instead of old traditional methods is crucial. In this study, we discuss ocean currents in the Oman Sea, suggest high-frequency radars (HFR) as new technology, and represent its advantages instead of ADCP. We use Mike 21 to get tidal current constituents and compare them with other data. The results show that values of two components, Mm and MSF, are more respective to astronomical-driven currents. Therefore, the amount of tidal current on the coast of Mokran is low, and other factors cause the current, which short-term observations in this region cannot be achieved. Thus, we need data in a more extended period to find present generating forces and predict them. HFR can be an efficient and valuable tool in such areas.
