The foundation for radar systems was laid by Christian Hülsmeyer when he obtained the first worldwide patent in radar technology on April 30, 1904 (patent DE 165 546). Six years later, Gotthelf Leimbach and Heinrich Löwy applied for a patent to locate buried objects using radar technology (patent DE 237 944). This …
