Near-Space Vehicles in Ground Moving Target Indication

Abstract

The last but not the least application of near-space vehicles in remote sensing is the Ground moving target indication (GMTI). In this chapter, we aim at MIMO SAR-based solution for GMTI including image formation processing. GMTI using MIMO SAR is interesting because the target indication performance can be improved by MIMO SARs' larger virtual aperture. The minimum detectable velocity of a target can be improved by both the larger virtual aperture size and the longer coherent processing interval used by MIMO SARs.
