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)()

FrequencyHoppingTechnology
在无线通信中使用跳频技术是军事通信中最主要的抗干扰手段之一, 而如果系统中能使用合适的中心频率可以快速跟踪跳频变化的带通滤波器将可以明显改善系统的抗干扰性能。文中从实际应用出发, 比较了几种可用于实现带通滤波器快速变频的方案, 选择了简单、实用的开关电容阵改变带通滤波器中心频率的方案(The use of frequency hopping in wireless communication technology is the most important anti-jamming in military communications, one of the means, and if the system can use the appropriate center frequency can be fast-tracked changes in frequency-hopping band-pass filter will be able to significantly improve the system anti-jamming性能. This paper from the actual application, the comparison of several band-pass filter can be used to achieve the rapid conversion of the program, choose a simple, practical switched capacitor array to change the center frequency of band-pass filter program)
