Abstract

The bispectral analysis techniques have been applied on signals received from the back-scattered signals by the MST radar. The results of this analysis are compared with that of the conventional power spectral analysis using the fast Fourier transform (FFT) technique. Our results showed that there is a significant advantage in using the bispectral technique over the conventional FFT technique. This study focuses on the importance of bispectral analysis in applications to atmospheric signals.
