Three-dimensional (3D) imaging technology based on antenna array is one of the most important 3D synthetic aperture radar (SAR) high resolution imaging modes. In this paper. a novel 3D imaging method is proposed for airborne down-looking sparse array SAR based on the imaging geometry and the characteristic of echo signal. The key point of the proposed algorithm is the introduction of ... https://www.kaliboat.com/product-category/grinders-food-servicecommercial-kitchen-equipmentfood-preparation-equipmentcommercial-meat-processing-equipmentmeat-choppers-industrialrestaurant/
