Heavy-tailed noise has more outliers than Gaussian noise, and traditional wavelet threshold cannot suppress outliers. A new method combining wavelet threshold and median filter is proposed. After suppressing the outliers in signal through median filter, the wavelet threshold is applied and remained noise is removed further. The experimental error analysis(More)
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(More)
