Abstract
In this paper, we present a method for generating synthetic aperture radar (SAR) video from multiple-input multiple-output (MIMO) video synthetic aperture radar (ViSAR) systems, which are suitable for operation in unmanned aerial vehicle (UAV) environments. This technique allows the analysis of stationary targets and moving targets in the SAR video. ViSAR systems are advantageous for detecting slowly moving targets since they have higher frame rates than conventional SAR systems. The MIMO ViSAR system is based on a frequency-modulated continuous wave (FMCW) SAR structure that is combined with multiple-input multiple-output (MIMO) technology, and multi-channel azimuth processing techniques. The results of analyses are presented, and their validity is verified using numerical simulations.
