Interference jamming DOA estimation algorithm

In this paper, the interference jamming method (IJM) is presented. The method can estimate the weak target under the condition of presence of large power interference of known direction. The method can be applied to the passive array radar based civil broadcasting station. The relation of the transform matrix and the restrained interference noise matrix is analyzed. Simulations are presented demonstrating the effect of the method.
