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)()
