1. 1. Detection and Depth Sounding of Small Targets with Airborne Laser Bathymetry

   Författare :Michael Tulldahl; Rainer Reuter; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : The subject of this thesis is an investigation of the potential for detecting small targets (size about 1 m3) with airborne scanning laser depth sounding. Examples of other optical techniques of interest for small target detection are: range gated imaging, polarized detection and passive multispectral imaging. LÄS MER

3. 2. Airborne laser depth sounding : model development concerning the detection of small objects on the sea bottom

   Författare :Michael Tulldahl; Linköpings universitet; []
   Nyckelord :lidar; depth sounding; remote sensing; ocean optics; laser beam transmission;

   Sammanfattning : Airborne laser depth sounding is a promising technique for rapid and high -density sounding of shallow waters. Depth accuracy analysis for laser depth sounding has almost exclusively dealt with horizontal flat bottoms. The objective of this work is to simulate and compare the influence of different shapes of small objects placed on the sea bottom. LÄS MER
