Fast analysis of electromagnetic scattering problems over a wide incident angle is always a difficult problem in computational electromagnetics. Up to the present, almost all of the traditional numerical methods need to solve one discrete angle after another to finish calculating this kind of problem. In this paper, we propose a new method, which can fix it effectively by applying compressed sensing into method of moments for magnetic field integral equation. The theory and calculation process of the solution are described in detail in the paper, and by numerical experiments of different three dimensional objects, the accuracy and the efficiency of the algorithm are also discussed.
