Cluster Analysis of Deep Water Sound Speed Profiles in Indian Ocean
Abstract Sound speed profiles in the ocean have a significant impact on the acoustic propagation, thus affecting the sonar detection performance. Sound speed profiles have characteristics of positional and seasonal distribution. In order to guide the sonar detection, use WOA13 dataset, calculate the...
