Broadband Mine Detection and Classification in Shallow Water
نویسندگان
چکیده
LONG-TERM GOALS Our long term goal is to advance development of underwater mine reconnaissance sonar for shallow water environments. Specifically, we wish to increase the range at which classification of mine-like returns can be done successfully (low probability of false alarms) and thus increase the reconnaissance area coverage rate. We also wish to improve the detection of buried mines in sandy bottom environments.
