Abstract

Abstract

En 中文
• Analyze the convergence characteristics of the single-angle iterative algorithm. • Find the reason why certain azimuthal frequency terms don’t converge or converge very slowly. • Present dual-angle iterative algorithm to resolve the convergence problem. • Present the method of obtaining the optimal second rotation angle.
