This paper develops methods for using frequency shift keying (FSK) Costas-coded transmission waveforms in order to generate synthetic aperture radar (SAR) imagery. This analysis examines the use of a specific Costas sequence waveform in order to generate FSK modulation. A matched correlation receiver is used to form SAR imagery corresponding to the transmitted Costas-coded waveforms. This investigation demonstrates the ability to generate SAR images via simulated radar measurement data collected by a notional radar platform that transmits and receives Costas-coded waveforms. This analysis examines the resulting spotlight-mode SAR imagery that are generated through the use of the Costas-coded transmission waveforms.
