Abstract

Multiple reflections on navy ship equipment cause unexpectedly high radar cross-section (RCS) distributions based on the location of each equipment on the ship. No RCS reduction method has been considered to date because the directions of reradiated electromagnetic waves are difficult to predict. In this study, an equipment arrangement design system for navy ships was developed to minimize RCS to reduce the radar detection range of naval ships by the enemy. To minimize the possibility of operating range interferences among equipment, optimal equipment arrangement areas and operation ranges were determined with reference to real navy ships. Various arrangements were tested by using a genetic algorithm (GA) to find the optimal positions with minimum RCS values within the areas of each equipment. Further, the radar detection range was considered from the perspective of survivability.
