本文提出了一种度量地空导弹武器系统抗干扰能力的方法:用抗干扰品质因数(Q_(AJ))来度量导弹武器系统的抗干扰能力。文中重点介绍了Q_(AJ)的定义及分析计算方法,并简要叙述了对空射击各阶段,干扰对武器系统作战能力的影响。 In this paper, a method of measuring the anti-jamming capability of surface-to-air missile weapon system is proposed. The anti-jamming capability of missile weapon system is measured by Q_ (AJ). This paper focuses on the definition of Q_ (AJ) and the analysis and calculation methods, and briefly describes the impact of air-to-air phase and interference on the combat effectiveness of weapon systems.
