为了提升激光半主动制导武器角度欺骗干扰效果评估方法的合理性,文中提出了一种新的综合评估方法,构建了一个比较全面系统的评估指标体系,综合考虑了告警成功率、时域相关度、波长一致性、空域相关度、码型匹配度、模式匹配度以及能量对比度等因素;并建立了计算引偏成功率的评价指标聚合模型以及计算干扰效果的杀伤概率下降程度计算模型。进一步,文中在简要介绍干扰效果评估基本流程的基础上,结合典型案例计算了激光角度欺骗干扰效果并分析了主要因素对干扰效果的影响,结果表明,缩短干扰反应时间、提高码型匹配度、增加干扰功率以及提高模式匹配度或使用双脉冲干扰方式都可以提高干扰效果。

With the purpose of promoting the feasibility of effectiveness estimation on laser angle deception jamming to semi-active laserguided weapon, a new method is proposed. A comprehensive evaluation index system is constructed that is composed of alarming success probability, time domain correlation, wave length consistency, spatial correlation, coding matching degree, model matching degree as well as interference-to-signal ratio (ISR). On the basis of this evaluation index system, the models of calculating the induced success probability and decline of kill probability are built. The basic flow of this evaluation method is introduced briefly, and a jamming effectiveness evaluating case is carried out by means of the method proposed by this paper. Furthermore the influences of main indexes on the jamming effectiveness are analyzed, and the results show that the jamming effectiveness could be improved by shortening the jamming reaction time, raising the coding matching degree, enhance the jamming power and increasing the model matching degree.
