He holds a total of six patents, showcasing his innovative spirit and technical expertise. His work has had a profound impact on various applications, particularly in military and telecommunications.

Latest Patents

Among his latest patents is the "Troposcatter diversity sidelobe jamming suppressor." This invention effectively suppresses sidelobe jamming in dual diversity troposcatter link receivers by utilizing an auxiliary low power antenna. The output from this auxiliary antenna is differenced from the high power main antenna signals before processing in the receiver's dual diversity demodulator. The auxiliary antenna's power is designed to be substantially equal to the sidelobe power of the main antennas, allowing for effective jamming power cancellation with minimal impact on desired signals.

Another significant patent is the "Signal source distortion compensator." This system is designed to reduce undesired amplitude, frequency, and phase distortions that arise due to variations in transmitted pulses. By averaging a plurality of sequential samples of transmitted pulses, the system determines filter coefficients that are then used in filters responding to received pulses. This innovative approach results in output signals with significantly reduced distortions.
