  • Interfering noise pulse eliminator and its use in a dicke type radiometer circuit
    Patent number: 4507661
    Abstract: An apparatus and method removes interfering noise pulses from low-level ro-frequency signals through the application of a video-frequency circuit which causes detection of interfering pulses above an automatically and dynamically established threshold voltage level. Upon detection of an interfering pulse a control signal activates a hold circuit causing the conventional radiometric circuit to be interrupted during the period of the occurrence of the interfering pulse, thereby blocking passage of the pulse, while simultaneously the voltage level of the video-frequency signal is held constant.

  • Radar radiometer and its use
    Patent number: 4347515
    Abstract: A radar radiometer apparatus including a superheterodyne amplifier, a synonous demodulator, and logic circuitry to provide for the interruption of a local oscillator for a portion of each pulse of a radio frequency repetition cycle in order to isolate radar receiver/transmitter coupling and permit simultaneous radiometer use.
