探雷声呐随机触点产生机理与分布

Generating Mechanism and Distribution of Random Contacts of Mine Detecting Sonar

摘要:

探雷声呐搜索水雷时会发现录取大量随机触点,导致分类辨识效率低下。 用海底微小目标的随机强反射特性解释随机触点的产生;运用聚类方法获得海底小目标的概率分布曲线,划分纯随机虚触点、 低重复虚目标和高重复似雷目标 3 个组成部分;提出直接剔除虚触点可有效提高辨识效率。

Abstract:

When mine detecting sonar searches mine, it will find a large number of random contacts, which leads to ineffi- cient classification and identification. The random strong reflection characteristics of small targets on the seabed are used to explain the generation of random contacts. The probability distribution curve of small target is obtained by clustering method. It is divided into 3 parts: pure random virtual contacts, low repetitive virtual target and high repetition mine-like target. It proposes that the iden- tification efficiency can be effectively improved by eliminating virtual contacts directly.
