Abstract

This research conducted an experiment on EAR-RASS acoustic chirp signal to find the better configuration for virtual temperature profile data retrieval. A single frequency acoustic pulses are susceptible to Doppler shift error, the utilization of continuous wave and chirped signals become a solution. Therefore, commonly the acoustic wave source is transmitted at different frequencies in order to meet wavelength condition for obtaining Bragg condition at wide range of altitudes. Several chirp configurations for EAR-RASS have been tested by changing their sweep range and time during these experiments. The ray-tracing method is applied before each experiment and confirmed by the Doppler spectra performance to ensure that the observation is conducted in the RASS echoes region. Compared to the other configuration, the 90-110 Hz has better performance as it produces highest echo power hence better virtual temperature data retrieval. [ABSTRACT FROM AUTHOR]
