small-target-detection-
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.)

ULA
已知：信号中心波长为2,天线阵元的间距为1米,快拍数为2000，空中有四个
源信号,假设它们的频率
四个源信号的方向分别为：
求：
1）在不加入噪声的情况下,观察并计算协方差矩阵特征值,并对它的特点
加以说明
2）分别采用MUSIC算法,CAPON算法, ESPRIT算法在下面四种情况下，对
上述四个信号源的波达方向进行估计,并画出它们的空间谱图；
①在不加入噪声的情况下,
②在加入高斯白噪声的情况下,假设信噪比为10dB
3）在信噪比变化范围为-20dB~+20dB时，分别采用MUSIC算法,CAPON算
法, ESPRIT算法，对上述四个信号源的波达方向进行估计,并画出波达方
向估计误差,随着信噪比变化的曲线图(即横轴为信噪比,纵轴为误差值)()
