视觉开发包(Visual development kit)

计算器，实现一个式子的加减计算，多个式子的计算，并测试结果(Calculator, to achieve a statement holds for addition and subtraction, multiple statement holds calculations, and test results)

说明：  采用6个发射机和9个接收机构成的观测系统观测目标，目标包含10个强散射中心，采用传统IFFT成像以及上述的多发多收构型下的单快拍稀疏成像方法，证明了多发多收构型下的稀疏成像方法在收发机个数较少的情况下能实现高分辨成像(An observation system composed of 6 transmitters and 9 receivers is used to observe the target. The target contains 10 strong scattering centers. The traditional IFFT imaging and the single-shot sparse imaging method in the above-mentioned multiple-transmit and multiple-receive configuration proves that there are multiple shots and multiple shots. The sparse imaging method in the compact configuration can achieve high-resolution imaging with a small number of transceivers)

说明：  修改的delphi Xe10框架，可在delphi Xe10.3下编译运行。适合初学的朋友参考(The Delphi XE 10.3 AppDemoS)

说明：  设计一八木天线，振子数目为4，长度分别为：反射器长度0.39，主馈振子长度0.356，引向器长度均为0.3；反射器和主馈振子的距离0.265，主馈振子和第一引向器的距离0.2575，第一引向器和第二引向器的距离0.225。天线工作频率为400MHz，各振子分段数为9。 利用矩量法模拟该天线的电流分布，并绘制方向图。(A eight wood antenna is designed. The number of vibrators is 4 and the length is 0.39 for the reflector, 0.356 for the main feeder and 0.3 for the director. The distance between the reflector and the main feeder is 0.265, 0.2575 for the main feeder and the first director. The distance between the first director and the second director is 0.225. The working frequency of the antenna is 400MHz and the number of segments of each vibrator is 9.)

利用泊松过程，实现泊松点过程和泊松簇过程(Poisson point process and poisson cluster process are realized by poisson process)

ceemd和eemd变换，用于信号处理，经过实际测试，可以运行(ceemd and eemd used for signal processing)
