DOI: 10.1109/lgrs.2022.3204169
Abstract: This letter focuses on ship target localization using a multistatic passive radar system based on navigation satellites opportunistic illuminators. In such systems, the typical approach to localize the target is taking peripheral decisions at each… read more here.
