Omega-k Algorithm Implementation for Linear Frequency Modulated-Continous Wave SAR Signal Processing

Abstract

The Omega-k algorithm is used for SAR systems due to the precision on focus quality in SAR raw signal. However, it is little explored for specific SAR systems such as Linear Frequency Modulated Continuous Wave LFM-CW systems. These systems are used to distance to target estimation, mapping, 3D modelling, etc. In this paper, the Omega-k algorithm is implemented for LFM-CW radars focusing real and simulated SAR raw signal determining algorithm focus quality parameters.
