Study on Development of Electro-Magnetic Environment Archive based on Total Recording Scheme and its Applications

我们研制了一种被称为“全记录系统(TRS)”的无线电波记录系统，其性能为400 MHz采样，磁盘存储容量为4TB。通过使用TRS，我们在当时还可以使用模拟电视广播服务的仙台进行了从100 kHz到200 MHz以上的无线电波环境测量。TRS不仅对于无线电波的记录和回放非常有用，而且对于传播环境分析也是非常有用的。我们还介绍了这种应用在超分辨DOA和延迟的虚拟阵列测量方面的应用。

We have developed a radiowave recording system called by “Total Recording System (TRS)”, the performance of which has 400MHz sampling with 4TB disk memory. By using the TRS, we carried out radiowave environment measurement from100kHz to over 200MHz in Sendai where the analog TV broadcasting service was still available at that time. The TRS is very useful not only for recording and play back of radio waves but also for propagation environment analysis. We also introduce such an application usage in terms of virtual array measurement of super-resolution DOAs and delays.
