摘要
建立了共形整流罩的模型结构,分析了其成像特性,并提出了采用加入衍射元件的方法来设计共形整流罩后的校正板,软件模拟结果表明带有衍射面的校正板能够进一步地改善共形整流罩成像质量.
Conformal dome may enhance the velocity and effective range of the missile systems by providing better aerodynamical surfaces than traditional domes. However, the highly aspheric surface may introduce serious aberration which changes with the field of regard,and the fixed corrector can be used to correct these higher aberrations in the big field. This paper analysis the performance of the conformal dome and proposes a way for the optical corrector design by adding diffractive element into the fixed corrector. The simulation proves it' s an effective way to improve the imaging quality of the conformal dome.
