Abstract
Naval operations in the littoral have to deal with threats at short range in cluttered environments with both neutral and hostile targets. On board naval vessels there is a need for fast identification, which is possible with a laser range profiler. Additionally, in a coast-surveillance scenario a laser range profiler can be used for identification of small sea-surface targets approaching the coast. An eye-safe 1.5 μm laser range profiler has been used to validate these claims. Experimental results show that range profiles of sea-surface targets can be obtained at ranges of several km's. Sea-surface clutter is shown to be negligible. Simulation shows that sea-surface targets can be distinguished from their range profiles. The influence on the identification performance of range resolution and a-priori knowledge of the aspect angle is presented. Classification has been tested on simulated range profiles of a number of small boats. With a range resolution of 0.3 meter (comparable to our experimental set-up), these small boats could be identified.
