Ultra-wideband widebeam SAR processing in the time-space domain

We propose an ultra-wideband widebeam SAR algorithm for processing in the time-space domain. The proposed algorithm can be interpreted as the time-space domain counterpart of the w-k domain ultra-wideband widebeam SAR algorithms published in recent years. The increased performance of the proposed algorithm against conventional SAR is demonstrated using real data obtained with an ultra-wideband widebeam ground penetrating radar system.
