Abstract

This paper presents a new technique based on the wavelet transforms for removing airplane and other transitory echoes in strato–tropospheric (ST) radar measurements. This technique provides a time–frequency display of the time series, which is necessary for discriminating the nearly continuous wind signal from transitory pollution such as airplane echoes. Very encouraging results obtained with the VHF INSU/Météo ST radar located at CNRM/Toulouse have shown practical possibilities for a real-time implementation and for applications related to frequency domain interferometry.
