激光武器对红外导引头毁伤机制与照射路径研究OA

To address the inadequacy of multi-level correlation in existing missile laser vulnerability modeling,this paper proposes a multi-scale hybrid modeling approach integrating system layer,struc-tural layer,and physical layer.Based on the functional and structural characteristics of short-range missile infrared seekers,combined with laser atmospheric transmission analysis and damage tree model,it establishes a three-tier evaluation system—'hard kill-blind-dazzle'to analyze damage thresholds for critical components.Research results indicate:the physical layer model reveals critical transition characteristics of damage patterns with distance;the structural layer model identifies opti-mal efficiency for hard-kill to the seeker when the irradiation path traverses the'three-component'region;the system layer model confirms detection capability failure as the most sensitive factor for overall hard-kill events.Through multi-level joint analysis,the focal plane detector array and image processing core module are identified as the critical strike targets.Consequently,a dynamic illumina-tion strategy is proposed that,at long ranges,it aims the'three-component'path coaxial with the core moduleas priority;at close ranges,it selects either the'four-component'or'six-component'path to achieve redundant destruction.
