红外末制导高速飞行器导引头参数综合设计研究

Study on Parameters Synthetic Design of Infrared Seeker for High Speed Aircraft Terminal Guidance

高速飞行器的弹道特点和结构特点对红外末制导的设计提出了较为苛刻的要求,导引头工作受目标特性、飞行弹道、头部空间、机动气动特性、控制系统的信息处理能力等多个总体因素制约,导引头参数的综合设计成为了总体初步方案设计的关键。总结提炼了红外末制导方案设计中与总体设计密切相关的设计要素,对各设计要素的关键指标与评价方法进行了研究,明确了红外末制导飞行器总体设计初期对各子系统设计需求。

Trajectory and structure characteristics of high speed guided aircraft bring new desire for infrared seeker terminal guidance design. Infrared seeker capability is restricted by various general factors, such as infrared target characteristics, flight trajectory, head space, pneumatic characteristics, and information process capability of control system. Synthetic design for seeker system parameters becomes the key of primary concept system scheme. This paper sums up essentials of infrared terminal guidance design which is closely related with missile design. The key index and evaluation methods for these essentials are presented herein. So it is clear about subsystem design desire at initial stage of aircraft general design.
