To address the urgent need to improve the ship type discrimination capability in maritime target detection. this article explores synthetic aperture radar (SAR) three-dimensional (3-D) imaging of moving ships. which can provide high robustness and stability of 3-D structural characteristics for ship type discrimination. This paper defines the three-degree-of-freedom (3-DOF) micro-Dopp... https://allfixelectricales.shop/product-category/handheld-vacuum-battery-charger/
