摘　　要：阐述了对于机载雷达,测高精度不高,特别是对远距离目标的测高精度更差,因而利用机载雷达提供的高度信息进行空海目标分类存在很大的不确定性.为了能有效地利用目标高度信息进行空海目标分类,把空海目标分类问题看成是一个u检验问题.首先,给出了用于空海目标分类的判别函数;然后,给出了一种决策规则,并推导出决策门限的计算公式和空中目标误判为海面目标的概率的计算公式;最后,通过仿真表明该算法的简易性和有效性.The accuracy of height finding of the airborne radar is inaccurate, especially, the accuracy is worse for the long-range target, so, using the target height information provided by airborne radar to airborne/sea target classification is rather uncertain. In order to use the target height information to airborne/sea target classification effectively, the problem of airborne/sea target classification is considered as a u testing problem. First, the discriminate function for airborne/sea target classification is presented. Then, a method of decision-making rule is given, and the computation formulae of the decision-making threshold and the probability of airborne target misjudged to sea target are derived. Finally, the simulation results show that the method is simple and effective.
