Use of P3-coded transmission waveforms to generate synthetic aperture radar images

This paper develops methods for using low probability of intercept (LPI) transmission waveforms in order to generate synthetic aperture radar (SAR) imagery. This analysis considers a specific transmission waveform based upon P3 codes in order to give phase shift keying (PSK) modulation. A matched correlation receiver is used to form SAR imagery corresponding to the transmitted P3-modulated waveforms. This analysis demonstrates the ability to generate SAR images based upon simulated radar measurements collected by a notional radar platform that can transmit and receive P3 waveforms. This work analyzes the resulting spotlight-mode SAR images that are generated using the P3 transmission waveforms.
