  • Methods and systems for mitigating noise for microwave remote sensing
    Patent number: 12540864
    Abstract: Radiometer systems and methods that mitigate flicker (1/f) noise are provided. A microwave radiometer system with accuracy impacted by 1/f noise comprises active components which, between measurements, are powered off and on. By powering the active components off and on, 1/f noise is mitigated. Disclosed systems and methods include performing a first measurement with a sensor of a radiometer, after performing the first measurement, switching power to one or more active components of the radiometer off, the active components comprising one or more of an amplifier, a square law detector, and an A/D converter, after switching the power to the one or more active components off, switching the power to the one or more active components on, and after switching the power to the one or more active components on, performing a second measurement with the sensor.
