“极低频探地(WEM)工程”是国家发展和改革委员会批准的“十一五”国家重大科学技术基础设施建设项目之一,用于资源探测和地震预测及其他前沿科学研究。文章对工程数据分析中所使用的窗函数进行了研究,深入分析了不同窗型对频谱泄露的影响,给出了相应的MATLAB仿真结果,提出了适用于极低频探地工程项目数据分析的窗型选择。
"Wireless Electro-Magnetic(WEM) project" is the national development and Reform Commission approved the the 11thfive-year plan national major science and technology infrastructure construction projects, research resources exploration and earthquake prediction and other frontier science. The window function for the engineering data analysis was studied, in-depth analysis of the different type of spectrum leakage, MATLAB corresponding simulation results, put forward for the selection window function for analysis WEM project engineering data.
