( 从太原市公交查询系统建立的必要性出发, 进行了公交查询算法的研究, 主要探讨了包括最短路径查
询及最少花费查询及数据库管理的公交查询系统的实现。 该系统采用了V ISU AL BA S IC 610 为开发工具,
M ICRO SO FT A CCESS2003 为后台数据库, 开发了基于太原市公交线路的公交查询系统。具有线路查询、换乘
查询、 站点查询、 数据管理等一系列功能。
((From the city bus system the need for inquiry, carrying out a public inquiry method of research, focused on the shortest path, including at least inquiries and inquiries and database management to spend the public inquiries system. The system uses a V ISU AL BA S IC 610 for the development of tools, M ICRO SO FT A CCESS2003 as the background database, developed based on the city' s public transportation bus lines inquiry system. with line inquiries, transfer information, site information, a series of functions such as data management.)

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)()
