摘要
导引头的抗干扰能力已成为衡量导弹性能的重要指标,针对常见的烟幕干扰,提出了激光/红外(IR)复合导引头的抗干扰策略。在分析烟幕对激光/红外制导干扰机理的基础上,分别就其对透射率与作用距离的影响展开分析计算。分析了目前红外成像导引头抗烟幕干扰的策略及存在的问题,并结合激光获取的目标距离信息,提出了复合抗干扰策略。
The anti-jamming capability of seekers has been one of the most important performance indexes to appraise the missile. Anti-jamming strategies of iadar/infrared （IR） composite seeker are proposed for the common smoke-screen jamming. Based on the analysis of interference mechanism, the impact on transmittance and range is calculated with respect to IR channel and ladar channel, respectively. The anti-jamming strategies and available problems of IR seekers are analyzed, then the composite anti-jamming strategy with target range information is proposed.
