In harbour environments operators should perform tasks as detection and classification. Present-day threats of smallobjects, as jet skis etc, should be detected, classified and recognized. Furthermore threat intention should be analysed. As harbour environments contain several hiding spaces, due to fixed and floating neutral objects, correct assessment of the threats is complicated when detection tracks are intermittently known. For this purpose we have analysed the capability of our image enhancement and detection technology to assess the performance of the algorithms in a harbour environment. Data were recorded in a warm harbour location. During these trials several small surfaces targets were used, that were equipped with ground truth equipment. In these environments short-range detection is mandatory, followed by immediate classification. Results of image enhancement and detection are shown. An analysis was made into the performance assessment of the detection algorithms
