SAR Imagery via Frequency Shift Keying Costas Coding
Garren_07944497.pdf (1.053Mb)Abstract
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.
