Amplitude and Phase Errors Correction for Array 3D SAR System Based on Single Prominent Point Like Target Echo Data
The Array 3D SAR has the ability of resolving imaging in three dimensions using the novel combination of linear array antennas and synthetic aperture. A practical array SAR system has the problem of multi-channel amplitude and phase errors, which can degrade the quality of the reconstruction image....

| description | The Array 3D SAR has the ability of resolving imaging in three dimensions using the novel combination of linear array antennas and synthetic aperture. A practical array SAR system has the problem of multi-channel amplitude and phase errors, which can degrade the quality of the reconstruction image. The echo model with amplitude and phase errors is presented. The effect of each errors are analyzed and a calibration method based on Single Prominent Point Like Target Echo Data is proposed. For the application of 3D imaging, the range migration algorithm with calibration scheme is also proposed. Simulations and real data processing are performed to validate the proposed calibration scheme. |
