红外搜索跟踪系统的目标截获判据

红外搜索跟踪（ＩＲＳＴ）系统在探测时对潜在目标的判别是系统工作的一个重要环节。通过建立目标的截获判据，提出了判决树多级识别方法和模糊综合评判方法，并为两种方法的融合使用提供了基础，为系统判别一般红外目标以及远距离小目标提供了依据和实现手段。

Acquisition Criterion for Infrared Searching and Tracking System

Discriminating the potential targets is an important step in detection of the infrared search and track (IRST) systems.By learning of the acquisition criterion of IR targets,the paper has put forward a decision tree discriminant method and a fuzzy integrated assessment method.It is also critical in the studies of the combined use of two methods.The work has given a convincing basis and instrumentality for the discrimination of IR ordinary targets and small long distance targets.
