摘　　要：为提高某型无人艇载设备的隐身性能,采用外形隐身设计技术,设计了一种满足无人艇安装要求的隐身防护罩,采用多层快速多极子与高频物理光学法混合算法(MLFMM+PO),在不同频率、不同探测仰角条件下对防护罩开展RCS仿真分析。仿真结果表明,随着防护罩周向各面内倾角增大,RCS平均值明显减小。仿真结果对相似艇载设备的隐身设计提供了有益参考。In order to improve the radar stealth performance of a type of unmanned vehicle-mounted equipment,a stealth shield is designed to meet the installation requirements of unmanned vehicle by using the shape stealth design,and the RCS simulation analysis of the shield is carried out at different frequencies and different detection elevation angles by using MLFMM+PO algorithm.The simulation results show that the average value of RCS decreases significantly as the circumferential inclination angle of the shield increases.The simulation results provide useful references for the stealth design of similar equipment.
