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

我们开发了一种无线电波记录系统，称为“总记录系统（TRS）”，其性能为400MHz采样和4TB磁盘内存。通过TRS，我们在当时模拟电视广播服务仍然可用的仙台进行了从100khz到200MHz以上的无线电波环境测量。TRS不仅对无线电波的记录和回放非常有用，而且对传播环境分析也很有用。我们还在超分辨率doa和延迟的虚拟阵列测量方面介绍了这种应用的用法。

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.
