Spectrum Solutions

行业领先的频谱专家

电磁频谱访问一直是军事行动的必要性。DOD频谱依赖系统的数量不断增加，再加上全球无线宽带行业对频谱的需求，使访问变得越来越复杂。电子攻击和网络技术的对抗性野战进一步使复杂性更加复杂。

With more than 65 years of experience across the lifecycle of spectrum-dependent systems, we are a proven leader in spectrum management and electromagnetic engineering. Our experts help the Armed Forces, the Department of Commerce, the intelligence community, other government agencies, and private companies optimize use of the electromagnetic environment, including resolving spectrum-sharing issues associated with the introduction of new radiating systems into already heavily congested co-platform, test, and contested environments.

Featured Work

TIREM RF Modeling TIREM RF Modeling
HII的地形综合地球模型（TIREM）使DOD和商业客户预测无规律的地形和海水的传播损失，用于地面和空中传播者和接收器。自1967年创建TIREM以来，HII科学家和工程师一直在增强和维护TIREM。

Clutter Model Approach Clutter Model Approach
HII is developing Propagation and Clutter Modeling Analysis (PACMAN), a new integrated model approach to help coordinate between the telecommunications industry (LTE and 5G providers) and the U.S. government. As part of this work, we have expedited early expansion to the AWS-3 bands, while continuing to protect DoD systems from harmful interference with increased accuracy, by modeling site-specific effects of clutter. Our approach provides an innovative, band-agnostic solution to clutter modeling that will benefit future bi-directional spectrum sharing analyses and build the foundation upon which a dynamic spectrum allocation engine could be developed to optimize shared spectrum use.
Commercial Regulatory Permissions Commercial Regulatory Permissions
HII在确保一家计划在美国通过低地球轨道卫星系统部署商业宽带服务的私人公司所需的监管许可。我们确定了适当的操作参数，以避免干扰现有系统，并提供分析和建议以推进文件。
Software-Defined Radio Design & Prototype Development Software-Defined Radio Design & Prototype Development
HII RF工程师使用了多种软件定义的无线电（SDR），并使用Zylinq 7000和Zynq Ultrascale+ System-A-A-Chip（SOC）构建了SDR，并能够生成复杂的波形，例如标准的通用数据链接（STD-CDL）。我们的设计过程同时使用HDL编码器和嵌入式编码器来靶向Xilinx FPGA和Xilinx Zynq Soc零件家族，从而允许在同一FPGA零件中进行浮点操作，以在高级还原指令集兼容机器（ARM）处理系统之间快速数据传输和FPGA可编程逻辑，用于复杂算法实现。
Emerging Spectrum Technology Emerging Spectrum Technology
必须将高级光谱技术集成到DOD的频谱依赖性系统中，以增强充血和有争议的电磁环境的访问和效率。HII是正式特许高级技术和政策/监管工作组的关键和积极合作伙伴。我们开发了模型和硬件内模拟，使我们能够提供有关频谱策略和策略的建议，并增强对现实情况下新兴频谱技术影响的理解。马里兰州的HII频谱运营中心包括一个频谱共享实验室，该实验室的重点是算法开发和RF信号处理。实验室人员与行业，研究人员和学术界合作设计和测试新技术，例如FPGA和芯片上的系统，MIMO，高级传感器和机器学习 - 可以提高访问，提高频谱认识，并提高频谱的意识，并提高频谱频谱共享。
