本工程实现了二维空间点的关于任意点的对称与关于任意直线的对称。(This project realizes the symmetry of arbitrary point and the symmetry of arbitrary line in two-dimensional space.)

他很反感；归属地分块地方好法国号法国号韩国胡富国(He was disgusted attribution to block a good place to Hu Fuguo French horn French horn Korea)

说明：  通过编写IDL语言，实现使用IDL语言进行分区统计功能。(By writing IDL language, the function of partition statistics using IDL language is realized.)

说明：   图像编码源代码，包括：PCX， GIF，LZW算法和GIF数据压缩，JPEG，TGA，TIFF等(Image coding the source code, including: PCX, GIF, LZW and GIF data compression algorithm, JPEG, TGA, TIFF, etc.)

能量检测法是一种比较简单的信号检测方法[1]， 属于信号的非相干的检测， 直接对时域信号采样值求模，然后平方即可得到；或利用FFT转换到频域，然后对频域信号求模平方也可得到。它无需知道检测信号的任何先验知识，对信号类型也不作限制。 实际上，能量检测是在一定频带范围内作能量积累，如果积累的能量高于一 定的门限，则说明信号的存在；如果低于一定的门限，则说明仅有噪声。能量检 测的出发点是信号加噪声的能量大于噪声的能量。能量检测方法对信号没有作任何假设，是一种盲检算法。 此代码“利用FFT转换到频域，然后对频域信号求模平方”方法来实现对用户的检测。(In fact, energy detection is used for energy accumulation in a certain frequency range. If the accumulated energy is higher than a certain threshold, the existence of the signal is indicated. If the threshold is lower than the threshold, then only noise is indicated. The starting point of energy detection is that the energy of signal plus noise is greater than that of noise. The energy detection method does not make any assumptions about the signal, and it is a blind detection algorithm. This code "converts the frequency domain into the frequency domain by FFT, then calculates the square of the square of the frequency domain signal" to realize the detection of the user.)

IDL读取txt，txt第一列是纬度，第二列是经度，第三列是DN值， 坐标转行列号 ，并以图像的形式输出(IDL reads TXT. The first column of TXT is latitude, the second column is longitude, and the third column is DN value. The coordinate turns the line and column number and outputs it in the form of image)
