A set of functionals and their consistent estimators have been developed for the spectral analysis of continuous non-stationary random processes. The methodology is suitable for analysis of discrete parameter non- stationary processes by using appropriate summations in lieu of integrations. The methods were developed to analyze modulation frequencies in radar returns from space vehicles re-entering the earths atmosphere. Good agreement is obtained between the spectral content of the radar returns through the use of these methods with data from other sensors. The method is most useful in determining spectral information from those processes whose frequencies change with time.
