热尾流红外探测作用距离工程估算方法

摘要

舰船热尾流产生的红外辐射特性是暴露舰船的重要非声物理特征之一。为实现对舰船热尾流红外特性的定量评估，本文从热尾流的产生，热尾流在海面产生红外辐射，热尾流产生的红外辐射在大气中传输和红外探测器的性能参数等影响热尾流探测的主要因素入手，建立各个部分的工程估算模型，形成红外探测作用距离的工程估算方法。分析红外探测的作用距离与热尾流特征参数的关系，为进一步研究热尾流红外隐身技术提供参考。%Ship′s infrared radiation characteristic caused by thermal wake has become important non-acoustic physics field characteristic which will result in ship′s exposure. To realize quantitative analysis of thermal wake′s infrared radiation characteristic, based on the analysis of impact factors sucn as thermal wake′s production,infrared radiation′s production on the sea surface,infrared radiation′s transmission in the atmosphere, and IR detector′s performance parameters, engineering evaluation model for every part is established, and engineering evaluation method for detection distance of ship by IR is formed. The relationship between detection distance by IR and thermal wake characteristic parameters is analyzed,so as to offer referrence to futher research of IR stealth technology.
