摘　　要：通过对大气激光散射信号的分析,给出了离轴距离与散射激光辐照度的关系曲线.计算分析表明,利用二元相关探测技术,在保持一定的探测概率和虚警率的情况下,可以近一步降低探测阈值,从而扩大激光告警接收机的警戒范围,提高激光告警器的散射截获能力.Through the analysis of the atmosphere laser scattering signal, the relation curve between the off-axis distance and scattering maximum radiation degree is provided. Based on the calculation analysis, by the two elements coherent detection technology, the detection threshold is further reduced, the scattering interception capability is improved and the warning field of laser warning receiver is increased.

关 键 词：阈值探测 相关探测 激光散射 离轴距离
