LabVIEW通过1200以太网
西门子S7-1200 PLC支持多种协议通过以太网通讯方式，如OPC、TCP、S7、MODBUS-TCP等。TCP方式相比其它协议，具有更多的灵活性，更快的数据响应等优点，本人即介绍LabVIEW通过TCP方式与S7-1200 PLC通信。
S7-1200 PLC的TCP通信方式，称之为“开放式用户通讯”，通过以太网发送或读取数据。(SIEMENS S7-1200 PLC supports a variety of protocols through Ethernet communications such as OPC, TCP, S7, MODBUS-TCP, and so on. Compared with other protocols, TCP has more flexibility, faster data response and so on. I introduce LabVIEW to communicate with S7-1200 PLC through TCP mode.
S7-1200 PLC TCP communication, known as "open user communications", send or read data over ethernet.)

radarechoSimulation
本文首先介绍了近些年来雷达模拟器获得广泛应用及其原因，然后对目标模
型、杂波模型和机载下视脉冲多普勒雷达的频谱分布进行了分析。接着，研究了
雷达回波信号模拟的实现方法，重点是采用网格映象法对地杂波信号的模拟进行
了分析和推导，并采用此方法对瑞利分布的高斯谱杂波、雷达回波信号进行了仿
真和分析。最后，针对用于某机载雷达信号模拟器系统的数字信号处理器进行了
设计和分析。
(This paper first introduces the radar simulator in recent years is widely available and the reasons for, and then on the target model, and the clutter model of airborne pulse Doppler radar, as under the spectrum distribution is analyzed. Then, to study radar signal simulation methods, with emphasis on the use of grid mapping method to the simulated clutter signal analysis and derivation, and use of this method, the Gaussian distribution of the Rayleigh spectrum of clutter, the radar echo signal simulation and analysis. Finally, for an airborne radar signal simulator system digital signal processor has been designed and analyzed.)

read_wav
说明： 读取wav音频数据的函数，可用于绘制WAV波形图，进行语音识别，哼唱别等。最基础的函数，但网上真正开源的C或C++版代码少，特别是将语音数据规范化的函数部分。代码是C++,但很容易改为C版，1:动态内存部分和释放内存的代码是C++的。2：求浮点型绝对值的fabsf函数是C++库里的。都是初学就有能力改成C版的。(Function of reading wav audio data(c plus version))
