Automatic Target Recognition Strategy for Synthetic Aperture Radar Images Based on Combined Discrimination Trees

Figure 8

Discrimination ability of various types of mother wavelets. The involved 47 mother wavelets are sequentially discrete Meyer wavelet, Biorthogonal wavelets (orders 1.1, 1.3, 1.5, 2.2, 2.4, 2.6, 2.8, 3.1, 3.3, 3.5, 3.7, 3.9, 4.4, 5.5, and 6.8), Coiflets (orders 1, 2, 3, 4, and 5), Haar wavelet, Daubechies wavelets (orders 2, 3, 4, 7, 10, 25, and 45), Reverse biorthogonal wavelets (orders 1.1, 1.3, 1.5, 2.2, 2.4, 2.6, 2.8, 3.1, 3.5, 3.7, 3.9, 4.4, 5.5, and 6.8), and Symlets (orders 2, 4, 8, and 16). The 37th mother wavelet is the Reverse biorthogonal wavelet 3.1.
