摘要
分析计算了激光在大气传输中在不同能见度下直接入射到告警接收机光电探测器表面上的信号辐射度,以及目标溅射和大气散射情形下的激光信号辐射度,对车载激光告警器灵敏度指标的确定进行了论证,为系统设计和研制提供了依据。灵敏度指标的确定是激光告警器设计的核心,该指标直接影响到告警器探测距离指标的确定。计算结果表明,灵敏度为毫瓦每平方厘米级的激光告警器能够探测到一般战术情况下经过接收器平台附近的激光信号。
The intensity of laser signal incident straightly on the surface of photoelectric detector of the warning apparatus was calculated under different atmospheric visibilities in this paper . Both the target reflection and the atmospheric dispersion were considered also. The sensitivity of the vehicular laser warning device was discussed to provide a guideline for the development and design of the device. It is a core to determine the sensitivity in the design of the device. It affects the determination of the reconnaissance distance directly. The calculation results show that the vehicular laser warning device of several mille watts per square centimeter in sensitivity can detect laser signal of target reflection and atmospheric dispersion in common tactics circumstance.
