Abstract
In this study, we investigated signal processing algorithm to reconstruct SAR image obtained from Frequency Modulated Continuous Wave - Synthetic Aperture Radar (FMCW-SAR). The airborne SAR raw data is usually obtained with continuous motion and non-linear (fluctuating) flight path. In order to compensate these effects, Back-Projection Algorithm (BPA) which can compensate the continuous motion effect was developed in this study. The algorithm was evaluated by applying it to the simulated and real-airborne SAR data.
