In Anti-Submarine Warfare operational scenario, sea-state is considered to be one of the most critical variables in active and passive sonar detection. Depending on type of sensor, the noise level created by wind waves will result in a minimum of ASW operational effectiveness. Currents play an important role in the re-distribution of physical properties of water which determines the sonar performance. In addition, data on current is essential for the safe and efficient operation and routing of marine traffic especially during the Southwest monsoon period. Considering these aspects, during the Southwest monsoon period of 2019, simultaneous data on surface current and wave parameters are collected using X-band radar system that is installed onboard INS Sagardhwani. This is the first set of data collected using the X-band Radar system in India. The advantage of X-band radar system over other remote sensing techniques is that it measures oceanographic parameters with very high spatial and temporal resolution. The survey is conducted along the track extending from off Kochi (Kerala) to off Port Blair (Andaman &Nicobar Islands) during July 18th to Sept 5th 2019. For the easiness of study, the survey area is divided into four, viz West coast India, east side of Srilanka, and west side of Srilanka and 10°channel. Southward currents with maximum speeds upto 0.6m/s is observed along the west coast of India. Predominant wave direction is southwest. The significant wave height is upto 3m with maximum wave height upto 4m. Maximum significant wave height is observed along the west coast of Sri Lanka. Here, the Hs is ranging upto 4m. But the predominant direction was WNW direction. The surface current direction is south-eastward with maximum the value of 1m/s. Strong north east currents speeds upto 1.5m/s is observed along the east coast of Sri Lanka and Southerly waves with Hs upto to 2m is also observed here. Compared to east coast of Sri Lanka, the current speed is less along 10° channel. North-eastward current upto 0.6m/s is recorded here. Southerly waves with Hs was upto 2m observed along 10° channel. Comparison of OSCAR with in-situ data in the study gives correlation coefficient of 0.77 and 0.78 for zonal and meridional components of current respectively. This study demonstrates the potential use of the X-band radar technology as a monitoring tool and to validate satellite derived data and the model results.
