Reduced-Dimension STAP Algorithm Based on Local Space Time Coupling Characteristics
Journal of Marine Science and EngineeringPatchy ionospheric clutter in high frequency surface wave radar (HFSWR) exhibits significant non-uniformity and local space time coupling characteristics. However, the best channel method (BCM) algorithm based on the maximum output signal-to-clutter-plus-

Multichannel analysis of medium grazing angle sea clutter
, 2022 S.1065-1068This paper investigates the impact of orbital water wave velocities on multichannel clutter characteristics. A theoretical sea clutter model was derived, which shows that the multichannel characteristics are different for sea clutter with ...

Speech characteristics that differentiate stuttering and cluttering in Japanese speakers
Frontiers in PsychologyBackgroundCluttering is a speech disorder distinct from stuttering. Despite this distinction, there is no established method to clearly differentiate the two disorders. This study aimed to use objective criteria to differentiate cluttering from stuttering in Japanese speakers.MethodsParticipants were 32 consecutive native-Japanese speakers who visited ...
