A New Channel Error Calibration Algorithm for Multichannel High-Resolution and Wide-Swath SAR Imaging Based on Subspace Fitting
High resolution and wide swath (HRWS) can be realized by azimuth multichannel synthetic aperture radar (SAR). However, system performance will be exacerbated by channel phase error. To solve this problem, this article presents an efficient channel error calibration method based on the fitting of the projection matrix. The validity of the proposed method is verified by the real-measured airborne SAR data.
