The primary aim of the present research is the determination of the extent to which radar systems efficiently and effectively execute the requirements and tasks associated with coastal surveillance. Hew (2006), a defence systems analyst with the Defence Science and Technology Organisation, contends that no single radar system is capable of fulfilling the stated tasks and responsibilities but that coastal area characteristics have to be matched against specific systems. In other words, the selection of the coastal radar selection system is dependant upon the characteristics of the coastal area in question and no radar system addresses the needs and features of all. Proceeding from an acknowledgement of this argument, this study will review all of radar technology, coastal surveillance requirements and existent methods for radar coastal surveillance to determine the optimal system, or systems for the execution of coastal surveillance responsibilities.As a strategy for responding to the selected researched question and satisfying the research's articulated aim, an in-depth investigative exploration of radar technology, coastal radar systems, and the requirements of coastal radar surveillance shall be undertaken. The results of the investigation shall determine the optimal coastal radar surveillance system(s).Prior to presenting the data upon which the discussion pertaining to the research question shall be based, it is necessary to contextualize the report's focus. This shall be done through a review of the definition for radar systems, an historical analysis of its development and the articulation of its responsibilities and tasks.
Practically all systems, from computer and communication systems to air and naval defense systems may ultimately be identified as multi-tasking technological networks, comprised of several asynchronous parallel distributed operations and whose total response is, by definition, both complex and probabilistic. Further evidencing the inherently complex nature of systems is the fact that operational responses vary in accordance to output events
