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)()

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.)
