  • Considering issue of target-aspect sensitivities in the waveform design for the recognition of broadband radar targets, a novel method termed Multi Eigen-Subspace (MES) is proposed in the additional of colored noise. The optimization is done via selecting a lot of eigenvectors which can represent the difference between the echoes of different classes of target in all aspect adequately and spanning them to several eigen-subspaces, then the optimized waveform will be obtained by mapping the desired waveform to those eigen-subspaces. The experimental results prove the efficiency of the proposed method. Compared to the available approaches, the MES waveform helps to increase the class separability and obtain the better performance.
