Research on a New Comprehensive CFAR (Comp-CFAR) Processing Method [PDF]
IEEE Access, 2019 Since the clutter statistics of marine radar are non-stationary and difficult to ascertain, the constant false-alarm rate (CFAR) processor based on some clutter statistical characteristics is hard to obtain the CFAR performance.

VIHCEMOS-CFAR Detector Based on Improved VI-CFAR
Journal of Physics: Conference Series, 2023 Abstract A variability index heterogeneous clutter estimate modified ordered statistics constant false alarm rate (VIHCEMOS-CFAR) detector based on improved VI-CFAR is proposed. First calculate the VI and MR values and then judge the clutter background: If the background is uniform, cell averaging (CA) target detection strategy is ...

Joint Ship Detection Based on Time-Frequency Domain and CFAR Methods with HF Radar
Remote Sensing, 2021 Compact high-frequency surface wave radar (HFSWR) plays a critical role in ship surveillance. Due to the wide antenna beam-width and low spatial gain, traditional constant false alarm rate (CFAR) detectors often induce a low detection probability.

Evaluación del desempeño de detectores CFAR
Iteckne, 2017 La operación de los radares costeros y oceánicos se ve afectada porque los blancos se encuentran embebidos en un fondo de clutter marino. De acuerdo con el criterio de Neyman-Pearson, los detectores de radar siempre buscan garantizar un valor determinado
