通过设置不同的参数利用Matlab软件仿真了不同场景下的系统性能 (This document suggests a user’s guide to a MATLAB application which simulates a Spatial Channel Model (SCM) based on reference [1] with some minor adjustments. It focuses on how to use the Graphical User Interfaces (GUIs) and the functions of the application and avoids going into specifics about the nature of the parameters as this is done analytically in the reference document)

用于对无人直升机进行操作杆控制的地面仿真程序，可实现对无人直升机的飞行方向、油门等的控制。(For unmanned helicopters operating lever to control ground simulation program can be realized on the direction of flight of unmanned helicopter, throttle and other controls.)

计算mie散射相关参数，根据颗粒粒径 ，入射光波长 ，颗粒折射率，介质折射率，计算不同角度下散射光强，不同粒径下的消光系数。(Calculate the mie scattering related parameters, calculate the scattered light intensity at different angles and the extinction coefficient at different particle sizes according to particle size, incident light wavelength, particle refractive index, and medium refractive index.)

复数计算，使用类来做的，可以选择自己要计算的方式(Complex calculation, using the class to do, and can choose their own way to calculate the)

ARTMAP source code. include: Fuzzy ARTMAP, Default ARTMAP, Instance-Counting ARTMAP, Distributed ARTMAP(ARTMAP source code. Include : Fuzzy ARTMAP, Default ARTMAP. Instance-Counting ARTMAP. Distributed ARTMAP)

读取雷达基础数据，将它保存在二进制文件中，然后可以通过读取基数据文件直接画图(Read radar base data, save it in a binary file, then you can read the base data files directly drawing)

1,、设置变量和参量： 　　X(n)为输入向量，或称为训练样本 　　W(n)为权值向量 　　e(n)为偏差 　　d(n)为期望输出 　　y(n)为实际输出 　　η为学习速率 　　n为迭代次数 　　2、初始化，赋给w(0)各一个较小的随机非零值，令n=0 　　3、对于一组输入样本x(n)和对应的期望输出d，计算 　　e(n)=d(n)-X^T(n)W(n) 　　W(n+1)=W(n)+ηX(n)e(n) 　　4、判断是否满足条件，若满足算法结束，若否n增加1，转入第3步继续执行(, set the variables and parameters: X (n) is the input vector, otherwise known as the training sample W (n) for the weight vector e (n) for the deviation d (n) is the desired output y (n) is the actual output η is the learning rate n is the number of iterations)
