| Abstract(in English) | Multi-channel SAR (Synthetic Aperture Radar) with low Pulse Repetition Frequency is effective for high-resolution wide-swath. Although reconstruction algorithm can relax the system's requirement of multi-channel SAR, noise enhancement occurs as adverse effect. One paper indicates that introduction of pseudo inverse matrix to reconstruction algorithm is effective for this problem. The study however has limitation of the Doppler frequency width in the output of reconstruction filter. Moreover, its performance has not been evaluated. In this paper, we formulate generalized reconstruction algorithm to resolve the noise enhancement. The result of evaluation with experimental data show that the proposed scheme can improve signal to noise power ratio up to 2dB. |
