| Abstract: | The application of wavelet transform to the 1 D target imaging of the step frequency MMW high definition radar was studied. The algorithm based on multirange cells was proposed using modulated Gaussian wavelet transform and good guality 1 D images of the radar target were obtained. The results indicate that the method is valuable for the improvement of target classification. |
