The physical meaning and application background of Frobenius norm modification method are expounded. The Frobenius modified scatter Matrix solution, it is proved that it is a positive scalar factor different from the Cameron modified scattering matrix, and the local optimality and uniqueness of the Frobenius norm modification method are proved. Finally, the performance of the two correction algorithms is verified by simulation experiments The conclusion of the article
