power_singlephaseASM.rar,功率电子领域matlab仿真文件，已经验证过，程序运行正常(power_singlephaseASM.rar,Power electronics field matlab simulation file, has already been verified, the normal operating procedures)

该代码通过对常规单脉冲雷达信号、LFM雷达信号和BPSK雷达信号通过wiger变换，得到三种信号的时频图，分析他们的时频关系和区别。(The code on conventional single-pulse radar signals, LFM radar signals and radar signals BPSK wiger transformation, three kinds of time-frequency map analysis of their relationship and when the frequency difference.)

多输入多输出技术 利用空时编码（stbc） 接收端采用分集接收技术(Multi-input multi-output air the coding stbc diversity reception technology)

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)
