说明: 介绍了经典的时频分布和检测理论的同时,作者利用时频分布的方法,将一
维时间信号转化到二维的时频空间中,通过提取图像的特征来判决信号和杂波,
采用的数据是使用McMaster IPIX雷达,在加拿大东海岸附近测得的。实测数据
研究表明此方法可以得到很好的检测结果。
(In this paper,we first review the time-frequency analysis and time
-frequency-based detection methods.Secondly,by analyzing a mass of the measured
data of sea clutter,we show the difference of time-frequency geometric features
between echoes with a target and pure sea clutter.Finally,we given the detection
algorithm based on the time-frequency geometric features.The results of the measured
data show that the proposed method can effectively find low-velocity small targets in
sea clutter.This approach is a novel try to detect small targets in sea clutter.)
