Latest Patents
One of Dudley's latest patents is titled "Quadrature mixture LO suppression via DSW DAC noise dither." This invention involves a Quadrature Error Corrected Digital Waveform Synthesizer (QECDWS) that employs frequency-dependent phase error corrections. The goal is to pre-distort the phase characteristic of the chirp to compensate for the frequency-dependent phase nonlinearity of RF and microwave subsystems. The QECDWS can also utilize frequency-dependent correction vectors to adjust the quadrature amplitude and phase of the synthesized output. This innovation effectively cancels the quadrature upconverter (mixer) errors, resulting in the direct generation of an RF waveform with a theoretical chirp bandwidth equal to the QECDWS clock frequency, which ranges from 1 to 1.2 GHz.
Another significant patent focuses on "Waveform synthesis for imaging and ranging applications." This invention provides frequency-dependent corrections for Local Oscillator (LO) feed-through. The operational procedure filters LO feed-through effects without requiring prior calibration or equalization. In synthetic aperture radar systems (SAR), a rolling phase shift is applied to the SAR's QDWS signal, allowing for the separation of unwanted energies from the desired signal. Calibration methods can also be integrated into the synthesis process to enhance signal quality.
