A scalable real-time processing chain for radar exploiting illuminators of opportunity
… receiver back-end, direct path interference and clutter suppression, range/Doppler processing and target detection are described and targeted to general purpose commercial off-the-shelf computing hardware. A detailed low level design of such a processing chain for commensal radar which includes …

Anti-jamming MTI radar using variable pulse-codes
… variation that degrades the integrated signal-to-clutter ratio by a factor of 1/N2 where N is the code length. This severely limits the ability to perform Doppler and Moving-Target Indication (MTI) processing for clutter suppression on the radar return. To recover this performance loss several …

Beamforming and scan pattern performance evaluation of rotating maritime multi-beam phased array surveillance radar
… only) processing algorithms were used. Complex clutter data sets from the CSIR Fynmeet sea clutter measurement trial were adapted according to the Georgia Institute of Technology (GIT) model, clutter area model and radar range equation to be inserted into each pulse. The output was a detection …

The dual-polarization radar signature of a wind turbine: characterization and suppression
… interference, also referred to as "wind turbine clutter," the construction and location of wind turbines is restricted, and radar operations are limited to suboptimal performance in the contaminated areas. With the exponential growth of wind energy production, reducing the interference caused by …

Backscatter Spatial Coherence for Ultrasonic Image Quality Characterization: Theory and Applications
… selection of acoustic output, 2) model-based clutter suppression in B-mode imaging, and 3) adaptive wall filtering in color flow imaging. </p><p>A novel image quality metric, known as the lag-one coherence (LOC), was introduced along with the theory that relates LOC to channel noise and the …
