Testing various time-frequency distribution techniques (U) / by Robert Klepko and Khanh N. Tran. : DR52-18/65-1992E-PDF
"The representation of a signal in both the time and frequency domains is a major topic of study in the area of signal processing. Over the past 40 years, many plausible derivations and approaches of time-frequency distributions have been suggested. This paper tests two time-frequency distributions and compares their results. The two distributions are the discrete versions of the Wigner-Ville and Choi-Williams distributions. This paper will demonstrate the capability of each distribution to resolve discrete sinusoidal and real radar signals simultaneously in time and frequency. The radar data represents backscatter from a ship on the open ocean. The results will be presented in both a graph and table format. These results will be compared to those obtained from the standard short-time Discrete Fourier Transform"--Abstract, page iii.
