| Abstract: | Azimuth resolution of meter wave radar can be improved by using super resolution spectrum estimation methods without extending the antenna aperture. In this paper, the real valued genetic algorithm was applied to the parametric super resolution approach for DOA estimation. The performance analysis was performed by computer simulation and the practical radar measured data. The results indicate that the global solution of real-valued genetic algorithm can improve the performance of azimuth super resolution for meter wave radar. |
