- Abstract
Factors that contribute to varying radar performance include internal causes such as equipment obsolescence, and external causes such as terrain and atmosphere. In particular, the atmosphere, which is a natural element, causes inevitable performance changes. The refractive index changes with atmospheric conditions in real time and affects the propagation environment, which affects the radar performance. Depending on the refractive index, atmospheric conditions are divided into super, sub, standard, normal, and trap, and the radar performance changes, such as the maximum detection range, occur differently during each atmospheric state. Therefore, it is important to predict and respond to changes in radar performance depending on the atmospheric conditions. In this study, the changes in the maximum detection range at low altitudes and detection performance at a long distance are analyzed using the M&S tool with respect to the refractive index. As a result, the maximum detection range decreases for a larger refractive index and vice versa, while the detection performance at a long distance changes because of abnormal atmospheric conditions.
