GprMax的理论基础是时域有限差分(FDTD)方法。时域有限差分方法直接将Maxwell方程作差分离散，利用二阶精度的中心差分近似把Maxwell方程中的微分算符直接转换为差分形式，在空间和时间上对电场和磁场交替间隔取样，使计算过程完全模拟电磁波逐步传播以及与目标物体相互作用的过程。(GprMax is based on the theory of the finite difference time domain (FDTD) method. The finite difference time domain method directly will Maxwell equation of discrete difference, using second order precision of the central difference in the equations are Maxwell approximate differential operator directly convert difference forms, in the space and time of electric field and magnetic field on alternate sampling interval, making the calculation process simulation electromagnetic wave propagation and completely step by step and target object interaction process. )

这个GUI程序让你测量面积和图像中路径的长度，实现了对面积和路径的测量。 (a gui which allow measuring an areas size and a paths length on an image (map). You can calibrate the image scale. You place points using left mouse button and remove points & areas with right mouse button. You have three different methods of measuring the area surface: 1. Monte-Carlo. 2. Triangulation (my method which works really cool but isn t optimal). 3. MATLABs way (which works the best).)

说明：  要：分析和研究了授权用户和认知用户共享频谱的一种算法的性能。 针对阴影效应或信道深衰落时，单用户频谱感知算法无法识别是频带未被 使用还是信道处于深衰落的情况，在频谱感知功率控制算法上进行了改进， 以克服这种算法的不足。改进后的算法能有效地控制认知用户的发射功率， 避免对授权用户产生有害的干扰。仿真结果表明改(To: analysis and research of the authorized users to share spectrum users and a cognitive performance of the algorithm. For the shadow effect or deep fading channel, the single-user spectrum sensing algorithm can not identify a band or a channel has not been used in the case of deep fading, the spectrum sensing power control algorithm has been improved on, to overcome the deficiencies of this method. The improved algorithm can effectively control the cognitive user' s transmit power, to avoid harmful interference with authorized users. Simulation results show that the change)
