摘要
针对利用高度信息进行空海目标分类时存在很大不确定性的问题,提出了一种机载雷达多门限空海目标分类方法。首先基于假设检验思想,利用高度估计值构建了空海目标分类判别函数,然后采用多门限决策规则进行空海目标分类,并结合统计理论,给出了各门限的计算公式。仿真表明该方法能够有效地进行空海目标分类,可同时将两类错误分类概率控制在较低水平。最后,给出了该方法的实际应用模型。
Due to the uncertainty of airborne/sea targets classification based on the target height information, a multi-threshold classified algorithm for airborne/sea targets is presented. First, a discriminant function for airborne/sea targets classification is constructed by using the hypothesis testing, Then a multi-threshold de cision-making rule is adopted to determine the decision thresholds. Simulation results show that the algorithm proposed can classify airborne/sea targets effectively, and the error probabilities are low. Finally, the practical model is given.
