摘　　要：本文基于多面角反射器的工作原理,设计了一种可以应用于模拟导弹头上的RCS增强器。为了满足模拟弹头在飞行过程中的动力、热力学环境的要求,对模拟弹头的外形结构和尺寸进行了规定。本设计在所规定的弹头空间内,通过设计一种圆形三面角反射器,再将多个圆形角反射器在弹头内进行合理排布,组成了一个RCS增强装置。经商业软件HFSS仿真计算并在微波暗室中实际测量,验证了在多频点下,当入射角在15°以内时,本设计对模拟弹头均具有大于4dB的RCS提升效果,实现了在C波段和X波段多频点下,对模拟导弹头RCS的增强效果。该设计可应用于检验防空武器装备的技术性能模拟试验中,可以解决模拟弹头RCS过小不易追踪探测的问题,具有一定的实际应用价值。This paper proposes an RCS enhancer for a simulated missile warhead based on the operating principle of polyhedral corner reflectors.The simulated warhead has specific shape and size in order to meet the dynamic and thermodynamic requirements during its flight.A circular trihedral reflector is designed for the limited warhead space conditions.Multiple circular reflectors are properly arranged in the warhead to form an RCS enhancement device.Through simulation calculation using the commercial software HFSS and actual test in a microwave anechoic chamber,it is verified that the proposed RCS enhancer can increase the RCS of the simulated warhead by more than 4dB at multiple frequencies when the incident angle is within 15°.It enhances the RCS of the simulated warhead at multiple frequencies in C band and X band.The proposed RCS enhancer can be used in technical performance simulation tests of air defense equipment to solve the problem that the simulated warheads are difficult to be tracked and detected because of their small RCS values.The proposed RCS enhancer has certain practical application value.
