红外系统协同探测性能分析

Performance analysis on co-detection of infrared systems

探测概率、虚警概率和作用距离是衡量红外探测系统最核心的性能指标。传统的分析方法只针对单个红外探测系统,随着多个红外系统协同探测的应用不断增多,迫切需要建立红外系统协同探测的性能分析方法。本文从单个红外探测系统出发,结合经典探测概率、虚警概率和作用距离的计算公式,基于二次累积探测原理分析协同探测时各性能指标提升的根本原因,并通过两个红外系统协同探测的示例直观展示了协同探测的性能提升效果,为红外探测系统的综合论证、协同样式分析等提供了重要依据。

Detection probability,false alarm probability and detection distance are the most important performances of the infrared detection system.Traditional performance analysis methods only consider single infrared detection system.As the co-detection applications of several infrared detecting systems increase,performance analysis method of co-detection is urgently necessary.Starting from the classic equations of detection probability,false alarm probability and detection distance for single infrared detection system,the root cause of performance improvement for co-detection is analyzed based on＂two-time accumulation detection＂theory.Taking co-detection of two infrared detecting systems as an example,the improved effect of co-detection is demonstrated.This provides an important reference for the demonstration and co-detection pattern analysis of infrared detection systems.
