Method and device for ship stealth performance optimization

The invention relates to the technical field of ship design, and discloses a ship stealth performance optimization method comprising the following steps: simulating and calculating the radar cross section RCS of each component of a ship; according to the simulation calculation result, distributing stealth performance indexes of all the components; and adjusting the stealth performance of part or all of the components until each component meets the stealth performance index. According to the method, radar scattering characteristics of each independent component of a ship can be analyzed according to each independent component under a preset simulation coding control scheme; a ship overall stealth performance preset index is refined to each independent component, and stealth performance optimization is carried out on each independent component; therefore, the stealth performance of the ship and exposed equipment on the surface of the ship is systematically optimized. The invention further discloses a device for
