Abstract

The purpose of this paper is to propose an adaptive processor implementing optimum moving target indicator (MTI) in the sense of maximizing the improvement factor (IF). Also, a multi-channel scheme for preventing coefficient fluctuation due to the presence of target echoes or impulse interferences is discussed. The proposed eignfilter recursively estimates the minimum eigenvector of the input clutter covariance matrix based on the inverse power method(IPM). In the proposed scheme, the IPM iteration is performed in a numerically efficient way using systolic processing architectures. Simulation results are presented to show the effectiveness of the proposed scheme.
