Detector Based on Fractal for Range extended Targets
This paper analyzes the statistical characteristic of clutter and that of signal plus clutter,and then a new detector of range extended target is proposed,which is based on box dimension of high resolution radar range profile.The box dimension is calculated as the detection statistic,and then is compared with the threshold.Finally,the detection performance of the proposed detector with different azimuths and in different clutter is analyzed.Experiment results show that the proposed method outperforms integrator in a certain azimuth,and its detection performance in non-Gaussian clutter is better than that in Gaussian clutter.In comparison with the energy accumulation method,the proposed method does not need to estimate the power level of the clutter and has strong applicability.It is also a CFAR detector.
