摘要
提出在四元红外导引头半实物仿真系统中采用“直接信号注入”技术,将仿真模型计算生成的具有目标、对抗和背景的动态红外场景,直接注入导引头电子舱,用于验证和调试导引头各种跟踪与抗干扰算法的有效性。讨论仿真系统的结构,目标运动、干扰弹投放和复杂背景的建模。在分析四元红外导引头工作原理的基础上,讨论动态红外场景信号的生成技术。最后介绍四元红外导引头半实物仿真系统的工程实现。
A ＂direct signal inject＂ method for hardware-in-the-loop simulation of four-element infrared seeker was proposed. Infrared scene comprised of target, countermeasure and background signals can be directly injected into the electronic cabin of seeker for verification and modification of the algorithms of tracking and anti-jamming. The architecture design of the simulation system was discussed in detail, and the modeling of target movement, interference missile and complex background scene was investigated. The dynamic infrared scene generation techniques were studied based on the four-element infrared seeking principle. And finally the implementation of the hardware-in-the-loop simulation system was given.
