模拟两个相干的的窄带信号。阵列的阵元数为10，快拍数为200，信号入射方向分别为20°，60°，阵元间距为入射信号波长的1／2，信噪比为20dB。分别用MUSIC算法和改进MUSIC算法进行仿真。仿真结果如下图所示(MUSIC algorithm is improved compared with the simulation of signal coherent MUSIC algorithm. Two coherent analog narrowband signal. Array element number of the array 10, the number of snapshots 200, a signal incident directions, respectively 20 °, 60 °, array element spacing is 1/2 of the wavelength of the incident signal, SNR is 20dB. Respectively MUSIC MUSIC algorithm and improved algorithm simulation.)

这一信道模型能够描述由电离层和对流层反射的短波信道，以及建筑物密集的城市环境。12瑞利衰落只适用于从发射机到接收机不存在直射信号（LoS，Line of Sight）的情况，否则应使用莱斯衰落信道作为信道模型(This channel model is able to describe the HF channel reflected by the ionosphere and troposphere, as well as building a dense urban environment. 12 Rayleigh fading only applies to from the transmitter to the receiver there is no direct signal (LoS, Line of Sight), otherwise use Rician fading channel as the channel model)

说明：  调频连续波雷达信号仿真，以及信号处理过程仿真，以三角波调制为例，代码编写规范，代码注释优秀。适合初学者以及急需FMCW信号仿真的用户(FMCW radar signal simulation, as well as signal processing simulation, take triangle wave modulation as an example, code writing is standard, code annotation is excellent. Suitable for beginners and users in urgent need of FMCW signal simulation)
