Monitoring of the virtual temperature profile by applying Frequency-domain Interferometric Imaging (FII) to RASS measurement

无线电声学探测系统（RASS）是一种具有高时间分辨率的测量温度廓线的雷达遥感系统。本研究旨在将FII（频域干涉成像）技术应用于RASS测量，以提高RASS测量的垂直分辨率。通过将上述技术应用于带RASS的MU雷达，使其垂直分辨率从常规技术的150米提高到60米。这项研究使我们能够在冲绳的RASS测量中实现白天连续无人操作。我们还尝试开发了观测表面边界层温度分布的新技术。

RASS (Radio Acoustic Sounding System) is a radar remote sensing system to measure temperature profile with a high temporal resolution. This study aims to improve the vertical resolution of RASS measurement by applying FII (Frequency-domain Interferometric Imaging) technique to RASS measurement. B y applying the above technique to the improvement of the vertical resolution with the MU radar with RASS was achieved to 60m from 150m in conventional technique. This study enabled us the daytime continuous unmanned operation of the RASS measurement in Okinawa. We also tried the development of the new technique to observe temperature profile in the surface boundary layer.
