摘要: 为支撑红外型空空导弹的中远射程发展,针对发射后截获技术应用,提出一种基于“信息装订+场景模型”的红外导引头探测距离估算方法。方法基于红外系统性能估计经典理论。通过对空战场目标特性的分析,完成了来自飞机和导弹控制系统的装订信息需求梳理,给出了估算方案框图和面向工程应用的设计示例。估算结果表明:该方法能够给出与实时态势匹配的距离估算结果,具有数据规模小、查询速度快、计算步骤少的优点,能够满足导弹有限资源下的高速应用需求。Abstract: To support the infrared air–air–missile development of medium and long ranges, an estimation method for the infrared seeker detection range is proposed. Lock-on-after-launch technology is employed. It is based on an "information binding and scene model". The method is based on the classical theory of infrared system performance estimation. Through the analysis of the environmental characteristics of the air battlefield, the information binding requirement from the aircraft or control system is completed. An estimate scheme block diagram and an example for engineering applications are given. The results show that the method can give distance estimation results that match the real-time situation, and it has the advantages of a small data scale, fast query speed, and minimal calculation steps. The method addresses real-time application needs under limited resources.
