THE CALCULATIONS OF SCATTERING CHARACTERISTICS OF ELECTRICALLY LARGE BODIES ON THE BASIS OF WAVELET-TRANSFORMATION

Currently, the tasks associated with the solution of electromagnetic scattering on complicated objects with electrically large size are considered in many practical applications. Conducting accurate and effective calculations for various conditions of electromagnetic radiation is a computational challenge to conventional electromagnetic approaches based on the method of moments, which requires a lot of memory, and there are requirements for computation time, because bodies of large size in comparison with the working wavelength. This paper presents a faster method using wavelet transforms in the calculation of scattering from large complex objects. Significant of the members in the matrix will be little, since the use of wavelets and, consequently, the induction current and equivalent magnetic current can be obtained quickly. In ad-dition, this approach can be used in conjunction with iterative methods.
