一种基于小波包变换的海面慢速小目标检测方法

摘要

This paper studies a kind of slow small target detection method based on wavelet-packet transform under sea clutter,and performs the computer simulation to the detection method by using the method that the slow target signal is added into the practical detection data of sea clutter.The simulation result shows that the method can detect the small target signal drowned in sea clutter background with better detection capability compared with general moving target detection（MTD） method.%研究了一种基于小波包变换的海杂波背景下的慢速小目标检测方法,并利用在实测海杂波数据中叠加慢速目标信号的方法对该检测方法进行了计算机仿真。仿真结果表明,与常规的动目标检测（MTD）方法相比,该方法能够以较高的检测能力对湮没在海杂波背景中的弱小目标信号进行检测。
