On the Derivation of Volume Decorrelation From TanDEM-X Bistatic Coherence

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2022
The bistatic interferometric coherence is affected by different sources of error, among which volume decorrelation, which quantifies the amount of noise caused by volume scattering mechanisms.

Using Radar Cross-Section to Enhance Situational Awareness Tools for Airport Avian Radars

open access: yesHuman-Wildlife Interactions, 2017
Digital avian radars can track bird movements continuously in the vicinity of airports without interruption. The result is a wealth of bird-track data that can be used in mitigation efforts to reduce bird strikes on and near airfields.
