Patents by Inventor Jerry D. Schmidt

Jerry D. Schmidt has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Apparatus for eliminating amplitude modulation interference in conically scanning radars
    Patent number: 4224622
    Abstract: The signal received through the fixed nonscanning transmitting lobe of the antenna in LORO conically scanning radar systems is demodulated to derive the interfering amplitude modulation. This modulation is then used to apply an amplitude modulation to the signal received through the scanning lobe that is equal and opposite in phase to the interfering modulation, thereby cancelling the interfering modulation and leaving only the modulation due to the conical scanning. Applications to both mechanically and electrically scanned systems are described.

  • Deception circuitry for automatic range gate tracking in fire control radar
    Patent number: 4164741
    Abstract: An acoustic delay line is used in a feed-back loop in the traveling wave tube repeater chain of an electronic countermeasures system to provide a wider transmitted pulse (than the pulse received by the ECM system) resulting in range gate deception in an opposing tracking radar.
