Study on Electromagnetic Scattering Characteristics of Bodies of Revolution by Compressive Sensing

Based on discrete wavelet transform (DWT), the discrete wavelet transform (DWT) is pre-processed on the basis of the Bodies of revolution-Method of Moments, and the underdetermined equation is constructed and solved by using the compressive perceptual method. In this method, non-zero lines are extracted from the sparse excitations of the wavelet coefficients, and a small-scale impedance matrix is formed to extract the impedance matrices, which reduce the memory consumption and improve the computational efficiency. This method of adding compression perception can systematically construct the corresponding underdetermined equations to ensure fast acquisition of the signal reconstruction solution.
