INTERPRETATION AND COMPARISON OF OUTPUT SIGNALS FROM LINEAR-FM PULSE-COMPRESSION SYSTEMS

Abstract

Several expressions for the output time function of a linear-FM pulse-compression filter, which have recently been derived, (ESD-TDR-64-128) are compared and interpreted. Comparisons are made analytically as well as graphically with respect to several pertinent parameters. It is shown that if the phase and envelope measurements of signals returned from an actual target were to be interpreted as though the signal had undergone a Doppler shift (instead of a time dilation), a considerable error would result for high target velocities. The feasibility of using an all-pulse-compression system for obtaining accurate estimates of radar target parameters is demonstrated. Simple analytic expressions, which describe the phase and envelope quite well during the time of measurement, are presented, and a procedure for properly interpreting the data is indicated.
