A case study of tsunami detection system and ocean wave imaging mechanism using radar

Tsunamis are the seismic generated waves, which causes the huge displacement of water volume in ocean from deep water to the coastal regions. Tsunami detection and investigation of its early warning is the very important issue nowadays, which supports our existing system more precise. This paper proposes a case study of the mathematical models of the ocean wave imaging schemes and the Tsunami detection system model for the Japan's region where Tsunamis hits on March 11, 2011. Tsunami detection function (q-factor) was developed which is well known as q-factor estimates. q-factor works on the principle of selected radar band threshold. The tsunami reaches around an hour afterward the earthquake, as specified through the relationship in the velocities in altered bands. These effects in a high-pitched upsurge in the q-factor, descriptive the tsunami appearance. This radar functions for only 40 min in the hour, causing in the 20 min gaps noticeable in plots. The entrance of the tsunami is specified by relationship between velocities in altered bands early about 2.5 h afterward the volcanic activity. q-factor demonstrates a sudden conversion in magnitude about 8 min afterward the start of the velocity relationships. At this point, the velocity is declining, representing that the tsunami is stirring offshore, subsequent in the negative q-factor. The future improvements in integrated tsunami detection systems can also be easily incorporated in this technique in order to obtain better detection capabilities.
