this program showing us the process of image enhancement

雷达/声纳正处理，常规巴特利特波束形成仿真。假设入射信号角度正横方向，M元接收阵对接收信号进行正负九十度的扫描。(Conventional beamforming for RADAR/SONAR. The source is supposed to be the broadband. there are M element array using for receiving.)

The TCRT1000/ TCRT1010 have a compact construction where the emitting-light source and the detector are arranged in the same direction to sense the presence of an object by using the reflective IR-beam from the object. The operating wavelength is 950 nm. The detector consists of a phototransistor.

线搜索求简单单峰值函数的最小值程序设计，算法采用固定搜索方向方法。(Simple single-peak line search function to find the minimum programming )

this program is an m-file of Model-based Predictive Control to track a sinusoidal target in various cases of mismatching and delay.

说明：  max3232分立元件内部结构图及其功能引脚。(max3232 discrete components within the structure and function pin.)

用matlab解方程，包括线性微分方程、非线性微分方程等等。(using Matlab solving equations, including linear differential equations, nonlinear differential equations and so on.)

在matlab上实现的遗传算法，采用二进制解码。很适合想用matlab实现自己的遗传算法的初学者，颇有参考价值(Genetic algorithm in matlab, using binary decoding. Very suitable for the genetic algorithm using matlab for beginners, are well worth)

里面包含多种综合评价方法，如层次分析法、模糊综合评判、基于可拓学的综合评价方法、数据包络分析法、TOPSIS分析法、熵权法以及人工神经网络分析法(It contains many comprehensive evaluation methods, such as analytic hierarchy process, fuzzy comprehensive evaluation, extension-based comprehensive evaluation method, data envelopment analysis method, TOPSIS analysis method, entropy weight method and artificial neural network analysis method.)

说明：  Simulink中实现PR控制器。PR控制器在逆变器控制中应用很多。PR控制能够在谐振频率处提供无穷大的增益，因而对谐振频率处的电流信号实现无静差跟踪，并且易于实现，可有效降低系统成本。(PR controller is implemented in Simulink. PR controller is widely used in inverter control. PR control can provide infinite gain at the resonant frequency, so the current signal at the resonant frequency can be tracked without static error, which is easy to implement and can effectively reduce the system cost.)
