Modelled sonar and target depth distributions for active sonar operations in realistic environments

Andreassen, Kristoffer Engedal; Hjelmervik, Karl Thomas (2022-09-08)

Target detection performance of mid-frequency active sonars depends heavily on both sonar and target depth. For a given target depth, a sonar performance model may help predict a sonar depth that maximizes the detection ...
Variability in modelled sonar and target depth distributions

Andreassen, Kristoffer Engedal; Hjelmervik, Karl Thomas (2024-06-26)

When attempting to detect a reflecting target using active sonar, the relationship between the sensor and target depths is of key importance. This is due to the non-uniform vertical sound speed profile in the water column, ...
