| titleOfInvention | A kind of radar target two-dimensional imaging method based on vortex electromagnetic wave |
| abstract | The invention discloses a kind of radar target two-dimensional imaging methods based on vortex electromagnetic wave.The present invention is based on the echo models that the vortex electromagnetic wave generated by uniform perimeter antenna array projects lower ideal scattering point, orbital angular momentum (OAM) mode is carried out to radar target signal and samples and calculate correlation function, obtain space spectral function with multiple signal classification (MUSIC) algorithm and carries out two-dimentional spectrum peak search to realize to Radar Target Elevation and azimuthal two-dimentional joint-detection.Scheme proposed by the present invention is compared with traditional angle of arrival (DOA) estimation scheme based on plane wave MUSIC algorithm, it can be realized higher angular resolution, scheme is imaged in the radar target azimuth relative to existing based on vortex electromagnetic wave simultaneously, under the premise of not increasing hardware costs while it can realize the imaging at target pitch angle, this has important references and reference to the Radar Design of modern New System. |
