MATLAB基础及应用 第2版电子教案 基础性非常好，适合新手。(MATLAB Fundamentals and Applications 2nd edition electronic teaching a very good foundation for novice.)

一维和二维阵列天线FFT分析，对不同间距的均匀阵列做了详细处理(1D and 2D array antenna analysis with FFT, and dealt with different inter-element distance.)

MIMO雷达是最近几年兴起的一种新体制雷达，能够有效地克服目标RCS闪烁，本程序模拟仿真了MIMO雷达在高斯噪声背景中的检测性能以及恒虚警检测的性能。(MIMO radar is the rise in recent years, a new system of radar, which can effectively overcome the target RCS flashes, the process simulation of the MIMO radar detection Gaussian noise in the background performance and CFAR detection performance.)

对系统辨识中白噪声信号的加入影响的分析，并进行在线辨识。(Identification of the system by adding white noise analysis of the impact of )

调频广播中，为了提高音频高频率端的信噪比，在发射端进行的预加重处理。(FM radio, in order to improve the high frequency end of the audio signal to noise ratio, performed at the transmitter pre-emphasis.)

说明：  异步电机的精确控制和速度辨识是交流传动系统中重要问题。在该仿真系统中，电机转速采用易于检测的电机定子电压和电流得到转速MRAS辨识算法来估算。由于速度辨识算法中电压模型的纯积分环节会引起的误差积累和漂移问题，采用改进积分型转子磁链估算模型来解决。(The precise control and the speed identification of AC motor are the very important issues on AC drive system.In this system, induction motor is controlled by the direct torque control, stator flux is estimated by u-n model observer that is effective in the full range of speed, motor speed is estimated by MRAS speed identification algorithm that is depended on the voltage and the current of motor stator easily detected. The modified integral rotor flux estimation model is used to solve the problem that the normal model can be affected by the error accumulation and drift of integral calculation in the voltage model of conventional speed identification algorithm. )
