Abstract :
In this paper airborne laser radar background signal is modelled with chaos (here the background signal means that received signal is back from sea surface and sea bottom without target such as submarine in the signal path). Based on the chaos definition we show in a convincing way that the background signal is chaotic by presenting the results of a detailed experimental study using real-life data collected from different experiment location. Based on the chaotic model a deep sea target detection method is presented which shows a satisfying performance
