Abstract: Rapid and accurate identification type of ship is essential for situation assessment and combat decision.In order to identify ships，with Bayes network，a kind of identification model of “two-step method ” is proposed，which makes use of character information of radar wave that return from ships.The experiment is carried out and the results coincide with the fact.This shows that the identification model is reasonable and effective.

Key words: Bayes network, characteristic information, target identification, two-step method

摘要： 快速准确地识别出舰船的类型，是进行战场态势评估和战场决策的基础。通过从远程侦察雷达的回波中提取特征信息，使用贝叶斯网络，提出了“两步法”对舰船进行识别，在此基础上进行了实例验证，其结果与事实相一致，显示了该方法的正确性和有效性。
