摘　　要：为了改善海天背景下对中远距离上的舰船目标的检测效果,本文简要分析中远距离上红外目标的一些基本特性,海天背景的主要全局特征。简单回顾了基于海天线特征的海上目标的检测方法,指出海天线特征对于中远距离目标检测所带来的不容忽视的不利影响。在此基础上围绕形态学重建构建了一种背景估计方法,实现对海天线特征的有效抑制,并取得良好的检测效果。To improve the effect of warship detection in mid-long range against a background of sea-sky,characteristics of IR targets in mid-long range are analyzed at first.The main features of sea-sky background are also introduced.Review of ship detecting methods which based on sea-sky line feature is given out.Problems and key technology to detect mid-long range target with sea-sky line background are analyzed.A method of background depression which utilize the morphological grayscale reconstruction is proposed.This method shows good performance in application.
