说明：  月球软着陆仿真：在停泊轨道上，探测器在脉冲制动的作用下，经霍曼变轨，下降到距月面大约 15 公里的近月点，该近月点就是主制动段的初始制动点。主制动段以下是障碍检测与规避和最终着陆段。在主制动段，由于探测器的初始速度很大(1.692km/s)，所以主制动段制导律设计的主要目的就是高效抵消此速度，将探测器导引到期望的末端状态(Lunar soft landing simulation: in the parking orbit, the probe under the action of pulse braking, through the hohmann change of orbit, to descend to about 15 kilometers from the surface of the moon, the near-moon point is the main braking section of the initial braking point. Following is the main braking section for obstacle detection and avoidance and the final landing section. In the main braking section, since the initial velocity of the detector is very large (1.692km/s), the main purpose of the guidance law design of the main braking section is to effectively offset this velocity and guide the detector to the desired terminal state)

该算法用于自回归输入模型，是一种迭代的算法。其基本思想是基于对数据先进行一次滤波处理，后利用普通最小二乘法对滤波后的数据进行辨识，进而获得无偏一致估计。但是当过程的输出信噪比比较大或模型参数较多时，这种数据白色化处理的可靠性就会下降，辨识结果往往会是有偏估计。数据要充分多，否则辨识精度下降。模型阶次不宜过高。初始值对辨识结果有较大影响。(The algorithm used for autoregressive input model, it is a kind of iterative algorithm. The basic idea is based on data to conduct a filtering processing, after using ordinary least square method to identify the data filter, and then obtain unbiased consensus estimates. But when the process output signal-to-noise ratio is larger or model parameters are too, this kind of data white processs reliability will drop, identification results tend to be biased estimate. Data should fully, otherwise the identification accuracy down. Model order time shoulds not be too high. Initial value to identification results have great influence on.)

matlab-hfss脚本文件的编写，含有周期性结构的脚本的编写，这个是之前都没人编写的。(Matlab-hfss scripts, file preparation, containing the preparation of the periodic structure of the script, this is a nobody before written.)

基于凸优化算法，频率分集阵列天线在全时空域内可控点聚焦，实现对动目标追踪、多目标聚焦，可用于实现点对点秘密通信(Based on convex optimization algorithm, the frequency diversity array antenna can focus on controllable points in the whole time and space domain, and can be used to realize point to point secret communication.)
