摘要:

来袭弹道导弹的系统发现概率是度量导弹探测系统效能的关键指标。基于搜索论,根据远程地基预警雷达分别在无目标指示和红外预警卫星目标方位、运动状态指示下的场景,分别建立了其对来袭弹道导弹发现概率模型。根据集合论给出了系统发现概率的定义和表达式,并分析了有目标指示相对于无目标指示状态的增量。以“铺路爪”远程预警雷达为算例,给出了其有无目标指示等多种情况发现概率的结果。研究过程可应用到导弹探测系统的设计。

Abstract:

Systemic detection probability for attacking ballistic missiles is a key factor to assess missile detection system performance. Based on search theory, under the condition of no target indicator and infrared early warning satellite indicator, the detection probability models of long-range earlywarning ground radar  aiming at ballistic missiles are set up respectively. According to the set theory, the paper proposes the definition and expression of systemic detection probability, and analyzes the increment between target indicator and no target indicator. Taking the “Pave Paws” radar as an example, the results of detection probability are provided under the condition with or without target indication. The research process can be applied to design the missile detection system.
