Land 3D: groups or single sensors? cables or radio? geophysical and operational considerations
Summary
Is the future of land acquisition systems in single sensors or groups? Cable, radio or no data telemetry (ie autonomous node) systems? Single or multi-component? Single sensors provide better signal than geophone groups; improved resolution and improved multi-component data. However,the increased noise with single sensors must be compensated with increased data density and more sophisticated data processing, and getting the value from shear waves seems more difficult than acquiring multi-component data. The potential operational advantage of systems without cables is in areas with limited access or if the receiver station interval is large. Cable based systems have operational advantages where cables can be deployed,receiver station intervals are small and the geophysical advantage of improved field QC.

陆上三维接收方式讨论
——数字检波器与检波器串、有线与无线对比分析
摘要
未来陆地三维地震采集系统是采用数字检波器还是模拟检波器组合？是有线、无线、还是无线遥测（如自动节电）系统？单分量还是多分量？数字检波器已被证明比常规的模拟检波器组合具有更好的信号特征，提高分辨率和及获得多分量数据。但数字检波器接收增加了噪音，必须通过增加数据密度和更精炼的处理方法去除，且要想从转换波中获得有价值的数据比采集多分量数据更为困难。无线接收系统潜在的优势是在限制进入的区域或者是接收间距大的地区。而有线系统在生产和技术上都具有优点：生产上的优点是可以采用小道距，而技术上的优点是更利于质量监控。
