Abstract :
A technique is described for the measurement of power spectra which is designed to distinguish the spectrum of a weak signal which is masked by strong background noise. The method was applied during the Jet Propulsion Laboratory Venus radar experiment to study spectral characteristics of the echo. An analysis is given which describes the performance of the system in such an application.
