无人艇载光电转台基于RCS的优化选型

为了减少无人艇被探测概率,降低无人艇整体雷达散射截面(RCS),对无人艇载常规外形光电转台散射源进行了分析,根据载荷需求,设计了特征尺寸相当的球形和U型光电转台,利用FEKO软件仿真比较了两型常规外形转台周向RCS变化,设计了封闭型、内倾壁面结构的六棱锥形光电转台,通过仿真比较,验证了周向RCS极值点和后向散射均优于常规外形光电转台.为无人艇载光电转台外形隐身设计优化选型提供了思路.

Optimal selection of USV photoelectric turntable based on RCS

In order to reduce the probability of unmanned surface vessel (USV) detection,reduce overall USV radar cross section (RCS),the general shape of USV shipbome photoelectric turntable scattering source is analyzed,according to the load demand,Design the equivalent characteristic size of spherical and U type photoelectric turntable,using FEKO software simulation and comparison of two types of conventional turntable circumferential shape the change of RCS,designed six pyramid shaped photoelectric enclosed type,the wall structure of the inclined turntable,the simulation results verify the circumferential RCS extremum and backscatter are better than conventional optical turret shape.It provides an idea for the design and optimization of the shape stealth of USV shipborne photoelectric turntable.
