The wavelet transform is used to make the matrix arising in the MOM solution of the magnetic field integral equation sparse, and then the induced current is obtained using the iterative method. Analysis and numerical tests show that the execution time is more effectively reduced with the help of the wavelet transform than the IM method based on the method of the moments hybird physical optics current, and this is useful in the RCS computation.
