Precise estimation of passive environmental microwave brightness temperatures in the presence of weak digital interfering signals

Summary form only given. Passive microwave remote sensing of naturally occurring thermal emissions is used to measure a wide variety of environmental parameters. For example, the ability to accurately estimate the power in such emissions directly impacts the reliability and precision of weather forecasts and data for environmental management. A leading contributor to the disability to accurately measure radiometric power for environmental applications is contamination of the signal by anthropogenic radio frequency interference.
