A Study of the Doppler Effects on the Detected Frank Polyphase Waveform.
Abstract
The doppler effects on the Frank polyphase coded waveform are studied by taking the waveform correlation function for many different values of doppler phase shift as related to a radar return signal. A doppler model, ambiguity function, and detection system are defined prior to the doppler study. Conclusions based principally on graphical observations of the detected waveform as well as deductive reasoning from mathematical formulation are stated in an orderly manner. Comparisons with the linear FM pulse compression system are made. Guidelines for treatment of doppler phase shift as a random process and studies in conjunction with other random processes are suggested. Postulated electronic countermeasures are treated briefly. Results of the study show that useful approximations of the detected output function can be made when the range and doppler are known. (Auhtor)
