Radar signal detection using fractal analysis in K-distributed clutter

Fractal theory has already been used in radar detection (Le et al., 1993). In this paper, a novel effective approach to detect target from K square clutter has been developed. The approach is based on the use of the fractal dimension estimated by box counting method. Based on this approach, the performance of fractal detector is compared with CA-CFAR detector. It is shown that it is possible to detect the presence of target by observing the fractal dimension of the radar returns especially when the signal-to-noise ration SNR is small.
