This study focuses on Tsunami detection using SIMRAD Radar. A tsunami is a condition in which sea waves overflow the land and cause severe damage, which can claim human lives, as well as important infrastructure such as schools, buildings, and housing on the coast. As a sovereign country and has resilience in various fields including security and ocean exploration, Indonesia must apply appropriate technology, in this case, a smart radar that can detect high sea waves from tens of km away even 100 km if radar capacity is maximized. And able to provide fast information for disaster emergency response teams to swiftly notify the surrounding community about the arrival of a tsunami, even predict before this tsunami hits the coast. In this research, a comprehensive measurement of the radar system is carried out. The radar used and developed is SIMRAD Radar Helo 6 and can be integrated with data from other hardware such as SBE 26Plus, to obtain comprehensive data about the marine environment. In the measurement process, several combinations of measurements are needed starting from how to get digital data, process digital data, and turn it into a real-time image in the form of a Graphical User Interface SIMRAD Radar Hello 6. In the search, SIMRAD Radar is placed on the coast, while SBE26Plus is placed in the ocean with a certain depth in the coastal area for seawater pressure and sea level measurement. This radar system can be converted from the SBE26Plus data results from the Acoustic Doppler Current Profiler (ADCP), and also SIMRAD real-time monitoring at the coastal position in a higher area to avoid obstacles.
