Sparse Representation Based SAR Vehicle Recognition along with Aspect Angle
Figure 3
The sparse representation vector and residual error of a test sample from SN_C71. (a) The sparse representation vector. (b) Residual error calculated with the complete sparse representation vector. (c) Residual error calculated with the sparse coefficients within a certain aspect range. The ground-truth aspect angle of the test sample is 307.01°, and the rectangle indicates the neighboring range around the aspect of the test sample.
