Achieving Efficient Spectrum Usage in Active and Passive Sensing Through a Market-Based Approach

分时使用频谱的机会可以显著提高频谱效率。频谱带宽的两个大用户--雷达和遥感--也是最有可能实现分时的两种应用。例如，雷达通常在方向上扫描，这可能允许在任何时刻都不被扫描的方向上使用雷达频率。通常使用Dicke切换在被观测源和内部校准源之间切换的遥感应用也可以在校准周期中进行分时。这项研究将调查将时间维度纳入频谱分配的情况，还将调查通过时间共享提供的频谱价值的相关市场评估。

Opportunities for time-sharing spectrum use could allow for significant improvements in spectrum efficiency. Two large users of spectrum bandwidth -- radar and remote sensing -- are also two applications that might best be able to allow time sharing. For example, radar usually sweeps in direction, which may allow use of the radar frequency in directions not being scanned at any one instant. Remote sensing applications, which often use Dicke switching to switch between the observed source and an internal calibration source, could also allow time sharing during the calibration cycle. The research will investigate the incorporation of a time dimension to spectral allocations, and will also investigate relevant market assessments of the value of spectrum made available through temporal sharing.
