摘　　要：为了提高岛礁背景下对红外目标的识别能力,提出了基于平均灰度的识别方法.红外探测器在对远距离舰船目标识别时,舰船附近与目标外型轮廓相似的海岛会给识别带来很大困难.通过对海岛和舰船的组成和红外特性的对比分析,以及从实地试验图像中得到的数据发现舰船的灰度平均值要高于海岛的灰度平均值.In order to improve the recognizing ability of the infrared objectives under the island＇s background, the recognition method is proposed based on average gray. While the infrared detector recognizes a ship as a target at the long distance, it＇s too difficult to identify it from the surrounding near the ship and the islands which have the exterior contour similar to the ship. Through researching the islands and the ships＇ component, comparing their infrared characteristics and as well as getting the data from the IR image, it is found that the average gray of the ship is higher than the island＇s average gray.
