Methods and systems for mitigating noise for microwave remote sensing

A method of using a radiometer, the method comprising:

• performing a first measurement with a sensor of the 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 power measurement device, and an A/D converter;
• after switching the power to the one or more active components off and prior to switching the power to the one or more active components on, wait a period of time sufficient for a voltage within each of the one or more active components to reach zero;
• 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.

A computer program product comprising:

• a non-transitory computer-readable storage medium having computer-readable program code embodied therewith, the computer-readable program code configured, when executed by a processor, to execute a method, the method comprising:
• 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 power measurement device, 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;
• in parallel with switching the power to the one or more active components off, processing the first measurement;
• and
• after switching the power to the one or more active components on, performing a second measurement with the sensor.
