摘　　要：红外光学系统是红外空空导弹的重要有机部分,其成像特性对导引头的性能具有极其重要的作用。本文对圆锥扫描光学系统的成像特性进行详细研究,首次利用转换矩阵的方法,推导出目标以及光学系统结构对像平面位置和像点扫描轨迹的影响关系,从理论上完善了圆锥扫描光学系统的原理,最后进行了相应的仿真实验论证。对比仿真结果与真实实物实验,表明该理论比较真实地反映了目标像点的扫描过程。本文对红外导引系统的分析与随后的信号处理具有现实意义。IR optical system is an important part of the air-to-air missile. Its imaging characteristics have an important influence on many performances of the IR seeker. A detailed analysis on the imaging characteristics of the cone scan optical system has been made. Firstly by using conversion matrix, the relationship among the targets, the optical configuration and the characteristics of the target images have been deduced. The principle of the cone scan optical system has been theoretically enriched. Finally the corresponding simulation and experiment have been made. The comparison on simulation results and corresponding experiment data show that the theory can substantially reflect the scanning process. Its results are realistically useful for the design and analysis of the infrared seeker system and the subsequent signal processing.
