The study is concerned with the identification of certain target characteristics through the analysis of received signals. Signal phase and amplitude as functions of time as well as the frequency spectra characteristics relating to discrete and distributed targets are investigated. The fundamental aspects of information received by a pulsed radar are reexamined with particular emphasis on the possibilities of extracting signature criteria from the signal phase as a function of the radar. Particular significance is attached to the stationarity of the phase for isolated point-targets, compared to the phase variations in the pulse associated with multiple targets entering and leaving the pulse pocket. Coherent phase discontinuities are analyzed in connection with regular distributions of point sources.
