Research Abstract

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.
