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)()

CMOS摄像头的智能监控系统
介绍了一种基于低成本CMOS摄像头的智能监控系统,实现了现场监控的实时化、智能化。系统可自动判别危险程度,可分别提供绿色、黄色和红色报警信息,并驱动相关附属设备工作。针对图像传输过程中的噪声,系统采用了对噪声图像使用局部算子的滤波技术来提高图像质量。根据对静态图像进行三原色分离后误差域的研究,达到背景与图像分离的目的,成功实现了图像的获取和处理。在低成本投入下,以简单的配置和简便的操作达到了高性能监控系统的功能。(Introduce a low-cost CMOS camera-based intelligent monitoring system, realize the scene in real-time monitoring and intelligent. The system can automatically determine the degree of risk, they can provide green, yellow and red alarm information, and drive the work-related ancillary equipment. For image transmission in the process of noise, system noise images of the use of local filtering operator technology to improve image quality. Based on static images RGB domain after the separation error research, background and images to achieve the purpose of separation, the successful implementation of the image acquisition and processing. Input in the low-cost, simple configuration and easy to operate to achieve a high-performance monitoring system.)
