Simulating the performance of laser imaging and range profiling of small surface vessels

The detection and classification of small surface targets at long ranges is a growing need for naval security. This paper will discuss simulations of a laser radar at 1.5 mu m aimed for search, detect and recognition of small maritime targets. The data for the laser radar system will be based on present and realistic future technology. The simulations will incorporate typical target movements at different sea states, vessel courses, effects of the atmosphere and for given laser system parameters also include different beam jitter. The laser pulse energy, repetition rate as well as the receiver and detector parameters have not been changed during the simulations. A discussion of the classification potential based on information in 1D, 2D and 3D data separately and in combination will be made vs. different environmental conditions and system parameters. System issues when combining the laser radar with IR/TV and a range-Doppler radar will also be commented.
