Underwater electromagnetic remote sensing

Utilization of non-destructive and non-invasive methods for the real-time underwater remote sensing is one of the challenging and desired tasks in the maritime security and safety as well as the harbour surveillance. Our aim was to develop and verify advanced electromagnetic sensors for a seabed objects detection and inspection. The seabed is a complex environment often covered with the sand, d...

Array Processing: Underwater Acoustic Source Localization

Compressive sensing underwater laser serial imaging system

Compressive sensing (CS) theory has drawn great interest in recent years and has led to new image acquisition techniques in many different fields. This research investigates a CS based active underwater laser serial imaging system, which employs a Spatial Light Modulator (SLM) at the source. A multi-scale polarity flipping measurement matrix and a model-assisted image reconstruction concept are...
