Abstract

This article addresses the use of the Fourier transform receiver as a radar system for high-resolution range-profile generation. A significant point of reference is the equivalence of this receiver to the standard matched filter. Henceforth, it is demonstrated that range information can be extracted from beat-frequency measurements by processing a selected set of waveforms. Attention is given to the step and hop-frequency modulation waveforms, which are shown to be easily compressed into an optimum range profile via coherent, narrowband processing. For these waveforms, the effects of velocity are also discussed in the context of profile distortion due to Doppler mismatch.
