  • Synthetic aperture radar for nonlinear trajectories using range relative doppler processing and invariant mapping
    Patent number: 5469167
    Abstract: Synthetic aperture radar imaging for nonlinear trajectories utilizing range relative doppler processing, invariant mapping of information from arbitrary shaped cells onto an X--Y coordinate system, and round trip signal delay which allows accurate synthesis of a reference signal for each range cell. A synthetic signal synthesizer produces the reference signal for synchronous demodulation in the radar.
