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.)

phase
设计了一基于现场可编程门阵列(FPGA)的低频数字式相位测量仪。该测量仪包括数字式移相信号发生器和相位测量仪两部分,分别完成移相信号的发生及其频率、相位差的预置及数字显示、发生信号的移相以及移相后信号相位差和频率的测量与显示几个功能。其中数字式移相信号发生器可以产生预置频率的正弦信号,也可产生预置相位差的两路同频正弦信号,并能显示预置频率或相位差值;相位测量仪能测量移相信号的频率、相位差的测量和显示。两个部分均采用基于FPGA的数字技术实现,使得该系统具有抗干扰能力强,
可靠性好等优点。()
