The radio detection and ranging (radar) is one useful instrument which a navigator uses to attempt safe navigation in poor visibility and night navigation. In the case of poor visibility and/or many similar targets in a close area, navigators sometimes make an error in recognizing the direction when they find the target in the landscape from radar information-target direction, distance, echo size, echo shape, sweep and relationship among targets' echoes. Also, they can make errors when finding the radar target's echo from the target information in the landscape. We have to prevent the errors to ensure safe navigation. The purpose of this paper is to find characteristics of target recognition using simulated marine radar in two steps: 1) to propose a model for radar target recognition; 2) to evaluate the errors of target recognition on the radar monitor by using two basic experiments.
