Fei Wang, Qi Ge, Jianjiang Zhou, Huawei Chen · 2010
Scattering centers estimation results are significant for radar target recognition in high frequency section. This paper introduces biquaternion theory into full-polarization scattering centers extraction of radar target. Firstly, we define full-polarization scattering centers as a biquaternion model. It makes a close connection between polarization parameters. Then, we propose Bihan's BQ-MUSIC thought to extract scattering centers' position parameters. Simulations illustrate that our theory gets better estimation results compared to polarization MUSIC algorithm of complex model.
