Digital surveillance of animals and nature recovery
People and Nature, EarlyView.Abstract Digital surveillance technologies (DSTs) are widely applied in nature recovery for their potential to generate novel data on species and ecosystems through digital tracking, automation (e.g. from hazardous locations) and from newly recruited citizen scientists.

Airborne Road Traffic Monitoring with Radar [PDF]
, 2007 To ensure mobility, future road traffic management needs actual and reliable information about the traffic over wide areas. Nowadays, outside of motorways the actual traffic situation is almost unknown due to the lack of sensor installations.

Quarterly Journal of the Royal Meteorological Society, EarlyView.A polarimetric radar forward operator to simulate differential reflectivity (ZDR$$ {Z}_{\mathrm{DR}} $$) from rain was developed to evaluate simulated storms in the Met Office Unified Model (MetUM) for two case days of the Wessex Convection Experiment (WesCon) field campaign. Vertical columns of ZDR$$ {Z}_{\mathrm{DR}} $$, indicative of strong updrafts,

Bistatic TerraSAR-X/F-SAR Spaceborne-Airborne SAR Experiment: Description, Data Processing and Results [PDF]
, 2010 We report about the first X-band spaceborne-airborne bistatic SAR experiment, using the German satellite TerraSAR-X as transmitter and DLR's new airborne radar system F-SAR as receiver. The data were acquired early November 2007.

Safety Science and Technology, EarlyView.We present an AI‐assisted ground‐penetrating radar framework to noninvasively detect and quantify smoldering wildfire‐induced subsurface cavities in peatlands. A ResNet model accurately predicts cavity geometry from GPR images, enabling improved assessment of underground fire damage and hazards.
