| 摘 要： | 研究了累积和检验算法应用于主动声呐信号检测时产生较大虚警数目的原因.实时处理时为减小运算量,采用非时变近似方法得出的低门限导致了虚警数目的增加;双门限的设置和限幅累积处理也是导致大虚警数目的原因.针对这2点,文中提出的新的单门限策略和累积流程通过对变化过程的充分累加能有效区分目标和干扰强度,降低虚警数目.海试数据的验证结果证明了该方法的有效性.

| Abstract: | The reason of a large amount of false-alarming interferences when the Page Test was used to detect active sonar signals is studied in this paper.The time-unvarying supposition of the nonlinearity parameter is used in real time processing in order to reduce calculating amounts results in increases of false-alarming interferences.The double-threshold design and the calculating algorithm also increase interferences.The new one-threshold design and the calculating algorithm proposed in this paper can effectivel... |
