Radiometry and contrast-to-noise ratio for continuous-wave and laser range-gated active imaging systems.

Applied Optics, 2023
Resolution and sensitivity must be considered in the design of an active imaging system. System sensitivity is characterized by the signal-to-noise or contrast-to-noise ratio and is derived through radiometry.

Soil Moisture Retrieval Depth of P- and L-Band Radiometry: Predictions and Observations

IEEE Transactions on Geoscience and Remote Sensing, 2021
The moisture retrieval depth is commonly held to be the approximately top 5 cm at L-band (~21-cm wavelength/1.41 GHz), which is seen as a limitation for hydrological applications.
