Latest Patents

Dewey's latest patents include a method of digitally demodulating a single sideband (SSB) signal. This invention features an SSB signal demodulator that comprises an analog bandpass filter for band-limiting the signal, an analog-to-digital converter for digitizing the band-limited signal, and a pair of quadrature-related decimating filters. The outputs of the Hilbert transform pair are used to obtain the upper or lower sideband signal, which is then reconverted to an analog signal. This innovative approach enhances the adjacent channel selectivity of the demodulator.

Another significant patent is for a horn antenna with a wide flare angle. This antenna is designed for an amplitude-comparison broadband direction-finding system with 360-degree azimuth coverage. The horn features a wide angle of flare and a cylindrical aperture, allowing for a substantially constant beamwidth over a broad frequency range. The design includes means for launching electromagnetic energy into the horn, ensuring effective propagation towards the aperture.
