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.

分时使用频谱的机会可以大大提高频谱效率。频谱带宽的两个大用户-雷达和遥感-也是最有可能允许分时的两种应用。例如，雷达通常在方向上扫描，这可以允许在任何一个时刻都不被扫描的方向上使用雷达频率。遥感应用通常使用迪凯开关在观测源和内部校准源之间切换，也可以在校准周期中实现分时。该研究将调查将时间维度纳入频谱分配，并调查通过时间共享提供的频谱价值的相关市场评估。
