Optimal waveforms design for radar imaging based on atomic decomposition RCS characteristics of target

Abstract

In this paper, we deals with the radar optimal waveform design problem using the atomic decomposition radar cross section (RCS) characteristics of target for radar imaging. The proposed method utilizes the radar target characteristics to design matched waveforms, For RCS characteristics of the given target, some signals can be obtained to have a better presented RCS characteristics of target by atomic decomposition method. The optimal signals derived from a target and noise environment. We defined a radar imaging performance by minimizing a distance measure between the reconstructed target RCS characteristics and the actual RCS characteristics. In simulation, we find that a approximation RCS characteristics of target can be obtained by a few atoms.
