However, this case exists widely in practical applications, especially in passive radar systems. In this paper, we propose a joint DOA and polarization estimation method for unequal power sources based on the reconstructed noise subspace. The invariance property of noise subspace（IPNS） to power of sources has been proved an effective method to estimate DOA of unequal power sources. We develop the IPNS method for joint DOA and polarization estimation based on a dual polarized array. Moreover, we propose an improved IPNS method based on the reconstructed noise subspace, which has higher resolution probability than the IPNS method. It is theoretically proved that the IPNS to power of sources is still valid when the eigenvalues of the noise subspace are changed artificially. Simulation results show that the resolution probability of the proposed method is enhanced compared with the methods based on the IPNS and the polarimetric multiple signal classification（MUSIC） method. Meanwhile, the proposed method has approximately the same estimation accuracy as the IPNS method for the weak source.展开更多

The spirit of Chinese culture concerns ethics and art. A good combination of moral and art education is the highest state of moral pursuit and artistic pursuit, as well. In the context of Chinese culture and art, music is more than a means to satisfy a person's physical appetite; it also serves to inspire people to cultivate a sound and complete personality. No art form can exist in isolation. Art should express the subject consciousness of individual artists and, more importantly, the common pursuit of all human beings. Such a philosophy should be reflected in every piece of artwork. The social guiding role of aesthetic education is a key feature of Chinese culture and there has been a civilizing influence pervading all aspects of Chinese culture and art. In a profound way, traditional Chinese art conveys the mental outlook and joy of Chinese culture. The fundamental humanism of Chinese culture is demonstrated in every aspect of Chinese art, which collectively highlights Chinese people's tastes and cultural pursuits. Therefore, it is easier to approach truths through art.展开更多
