By enlarging or shrinking the window size, the background data taken into account respectively increases or decreases, and thus the filtered image accordingly includes much clutter or less clutter with target information loss. In this study, a novel adaptive clutter removing procedure based on ...

In Fig. 6(d), the center beam energy is high; the CFAR method based on the transverse window did not take into account the longitudinal interference information of the target, so there were a large number of false alarms in the strong beam region. The results for the 1D longitudinal ...
CFAR (S-CFAR), that takes into account the amplitude of the test cell for reference sample selection, has been proposed in [15]. The unique structure of the S-CFAR is its switching action, which allows the processor to select: (i) either only ...

In SRSDD, nearshore scenes account for 63.1%, while offshore scenes make up 36.9%. To ensure the fairness of experimental results, our experiments follow the same protocol as in the literature [37], which uses 532 images for training and 134 images for testing. In both the training and ...
