说明：  关于正交信号中，复数的意义，其实复数是有实际意义的！(On the quadrature signal, the plural meaning, in fact, there is a complex meaningful!)

Nelder-Mead法用于多维变量的最优化问题，维数>=2.(Nelder-Mead method for multidimensional optimization problem variables, dimension> = 2.)

说明：  在2d不光滑曲面上的射线跟踪算法，效果比较好，希望可以帮助到大家(2d surface is not smooth in the ray-tracing algorithm, the effect is good, hope you can help to)

瑞利信道_帧：128个0，128个PN (Rayleigh channel _ Frame: 128 0,128 a PN)

说明：  关于脉冲压缩的问题 。脉冲压缩的质量直接 影响雷达的探测性能。经典的脉冲压缩是通过匹 配滤波器来实现的[1 ] 。从本质上讲 ,脉冲压缩是对 发射信号的匹配滤波 ,但由于不同的目标回波信 号带有不同的多普勒信息 ,具有不确定性 ,所以它 只能是准匹配滤波(Pulse compression on the issue. Direct impact on the quality of pulse compression radar detection performance. Classical matched filter pulse compression is achieved by [1]. In essence, the pulse compression is a matched filtering the transmitted signal, but the different echo signals with different Doppler information is uncertain, it can only be quasi-matched filter)

在matlab中很适用，很经典的产生几种测试噪声的程序。(In matlab it is applicable, it is the classic noise generated several test procedures.)

matlab 基础上通过最小二乘法进行模态参数识别，得出固有频率，振型，阻尼比，图形(by the least squares method matlab based on the identification of modal parameters obtained natural frequency, mode shape, damping ratio, graphics)

Monte Carlo方法的实质是通过大量随机试验，利用概率论解决问题的一种数值方法，基本思想是基于概率和体积间的相似性。它和Simulation有细微区别。单独的Simulation只是模拟一些随机的运动，其结果是不确定的；Monte Carlo在计算的中间过程中出现的数是随机的，但是它要解决的问题的结果却是确定的。(The essence of the Monte Carlo method is a numerical method to solve the problem through a large number of randomized trials, the use of probability theory, the basic idea is based on the similarity between the probability and volume. There are subtle differences between it and Simulation. Separate the Simulation simulation of random movement, the result is uncertain number of the Monte Carlo calculations in the middle of the process is random, but it is to solve the problem the result is determined.)
