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.)
