This Small Business Innovation Research (SBIR) Phase I project will integrate a new free-space low frequency electric field (E) sensor with a miniaturized magnetic induction (B) sensorto form a compact six channel sensor package. The proposed new E and B sensor offers a completely new instrumentation capability for geosciences, providing for the first time measurement of the full electromagnetic field vector in a compact package without contact to the ground or any other physical object. The Phase I objectives are to study the trade-offs involved in reducing the overall sensor volume to allow airborne operation, and the use of multiple baseline methods for cancellation of local noise. The application of the new sensor to a variety of geosciences applications ranging from the measurement of ULF atmospheric phenomena and lightning characterization, to magnetotellurics from a mobile platform will be studied. In Phase II a full prototype will be built and tested for the most promising applications.Commercial applications include general research instrumentation for low frequency electromagnetic fields, atmospheric electromagnetic phenomena, military sensors, and complete systems for potential new applications in lighting characterization and airborne magnetotellurics.

这一小型企业创新研究（SBIR）第一阶段项目将把一个新的自由空间低频电场（E）传感器与一个小型化磁感应（B）传感器集成在一起，形成一个紧凑的六通道传感器封装。拟议中的新E和B传感器为地球科学提供了一种全新的仪器能力，首次在不接触地面或任何其他物理对象的情况下，在紧凑的封装中提供完整的电磁场矢量测量。第一阶段的目标是研究在减少整体传感器的体积，允许机载操作，并使用多个基线的方法来消除当地的噪音所涉及的权衡。将研究新传感器在各种地球科学应用中的应用，从ULF大气现象和闪电特征的测量，到来自移动的平台的大地电磁学。在第二阶段，将建立一个完整的原型，并测试最有前途的应用。商业应用包括低频电磁场，大气电磁现象，军事传感器的一般研究仪器，并在照明特性和航空大地电磁学的潜在新应用的完整系统。
