The Dynamic Sea Clutter Simulation of Shore-Based Radar Based on Stokes Waves
Remote Sensing, 2022 The sea clutter model based on the physical sea surface can simulate radar echo at different times and positions and is more suitable for describing dynamic sea clutter than the traditional models based on statistical significance. However, when applying

Automatic insect identification, counting, and monitoring techniques: a review
Pest Management Science, EarlyView.Automated insect monitoring increasingly integrates optical, acoustic, infrared, radar, electrostatic, and biosensing technologies with artificial intelligence. No single approach is universally optimal; reliable deployment depends on task‐specific validation, representative datasets, robustness under field conditions, energy autonomy, connectivity ...

Clutter Suppression Approach for End-Fire Array Airborne Radar Based on Adaptive Segmentation
IEEE Access, 2019 End-fire array antenna is a kind of special radar antenna with beam pointing perpendicular to the normal direction of the array. Because of its low profile and directional radiation characteristics, it is especially suitable for blind zone compensation ...

Enhancing severe convection forecasts with microwave radiance assimilation in limited‐area models
Quarterly Journal of the Royal Meteorological Society, EarlyView.Microwave satellite radiances remain largely underexploited in convection‐permitting limited‐area models. We assess the assimilation of humidity‐sensitive radiances from the MHS instrument in the operational ICON‐2I model, improving the precipitation forecast of a severe convective event over the Marche region, Italy, substantially by correcting ...

Quarterly Journal of the Royal Meteorological Society, EarlyView.Precipitation growth and decay due to orography was analyzed using the radar network in Great Britain. Storm direction and speed modulate the intensity of precipitation growth or decay. Windward slopes predominantly exhibit precipitation growth, while leeward areas show precipitation decay.

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.

Doppler-Spread Clutter Suppression in Single-Channel Noise Radar
, 2022 S.881-883Continuous emission noise radars suffer from the problem of reduced sensitivity due to masking effects caused by the side-lobes of direct signal leakage, clutter returns and echoes of close targets.
