Study of pulsed radar spectra

Abstract

<p>In a pulsed radar system, due to the existence of incidental frequency and amplitude modulation, the spectrium of the transmitted RF pulse may deviate markedly from the ideal form. It is the purpose of this thesis to study the spectra of pulsed RF signals with different forms of incidental frequency modulation and amplitude modulation.</p> <p>The contribution of this thesis may be summarized as follows:</p> <p>(1) A phenomenological approach to the analysis of pulsed RF signals containing incidental modulation has been developed using the Fast Fourier transform method.</p> <p>(2) A fairly general analytical formula has been developed for the pulsed RF spectra, using the convolution integral.</p> <p>(3) A real-time experimental simulation of pulsed signals with incidental modulation has been successfully designed to measure the pulsed RF spectra.</p> <p>Close agreements between the results of these three approaches has been demonstrated.</p>
