代码说明:

  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)()

    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.)
