Range-Dependent Folded Clutter Suppression for IPPAW-Based Side-Looking Airborne Radar in Nonhomogeneous Environments

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Side-looking airborne radar (SLAR) systems employing conventional waveforms suffer from range ambiguity, whereby near-range clutter is folded into the same range segment as far-range low-velocity target echoes, thereby degrading target detection ...

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 ...

Modified matched filter for cloud clutter suppression [PDF]

IEEE Transactions on Pattern Analysis and Machine Intelligence, 1990
The least-mean-square (LMS) filter has been developed as an alternative to the classical matched filter (MF) to address the clutter-spectrum issue. However, the output of the MF and the LMS processes is dependent on the scene energy and marginally dependent on the filter signal shape.

Surface Clutter Suppression Techniques for Ice Sounding Radars: Analysis of Airborne Data [PDF]

, 2008
For the ice sounding of Antarctica from space, a P-band radar at 435 MHz is the only option which complies with present ITU regulations. At this frequency the ice surface cannot be considered smooth, leading to high ambiguous returns.

Nonreciprocal Swarmalators With Reconfigurable and Controllable Formations for Robot Collectives

Advanced Robotics Research, EarlyView.
Nonreciprocal swarmalator interactions are enabled through control barrier functions to transform self‐organizing robot collectives into reconfigurable, constraint‐aware systems. Complex two‐ and three‐dimensional shapes, continuous morphing, obstacle‐aware navigation, collective splitting, and object transport emerge from modulating agent‐level ...

UC Food Waste: A Multimodal Robotic Perception Dataset for Robust Contaminant Detection in Complex Biowaste Scenes

Advanced Robotics Research, EarlyView.
A balanced multimodal food‐waste dataset and a novel Split Spatial‐Spectral Attention fusion framework are presented for robotic contaminant detection. Separate processing of RGB, thermal, and multispectral inputs preserves subtle material signatures before feature integration, reducing modality interference and improving classification and ...

Suppression of Non-Gaussian Clutter from Subspace Interference

, 2020
In complex electromagnetic environments, a clutter covariance matrix is required to estimate in the on-line manner, so as to adaptively adjust the filter weight to effectively suppress clutter, thereby improving target estimation, detection, location ...
