Abstract: For high-resolution radar, target recognition is performed by using 1D range profile.In this method, a radar target is described as composed of several kinds of scattering centers with different geometric shapes and structures. However, 1D range profile is so extremely sensitive to aspect angle that a useful target recognition procedure is very unlikely to evolve from it. Here, a study is performed ion the fractal characterization of 1D range profiles of high-resolution polarimetric radar targets at four kinds of polarimetric states and a new concept of the fractal matrix is proposed. !4
