Abstract: The Recognized Maritime Picture (RMP) is defined as acomposite picture of activity over a maritime area ofinterest. In simplistic terms, building an RAMP comesdown to finding if an object of interest, a ship in ourcase, is there or not, determining what it is,determining what it is doing and determining if sometype of follow-on action is required. The CanadianDepartment of National Defence currently has access toor may, in the near future, have access to a number ofcivilians, military and allied information or sensorsystems to accomplish these purposes. These systemsinclude automatic self-reporting positional systems,air patrol surveillance systems, high frequency surfaceradars, electronic intelligence systems, radar spacesystems and high frequency direction finding sensors.The ability to make full use of these systems islimited by the existing capability to fuse data fromall sources in a timely, accurate and complete manner.This paper presents an information fusion systems underdevelopment that correlates and fuses these informationand sensor data sources. This fusion system, namedAdaptive Fuzzy Logic Correlator, correlates theinformation in batch but fuses and constructs shiptracks sequentially. It applies standard Kalman filtertechniques and fuzzy logic correlation techniques. Wepropose a set of recommendations that should improvethe ship identification process. Particularly it isproposed to utilize as many non-redundant sources ofinformation as possible that address specific vesselattributes. Another important recommendation statesthat the information fusion and data associationtechniques should be capable of dealing with incompleteand imprecise information. Some fuzzy logic techniquescapable of tolerating imprecise and dissimilar data areproposed.!13
