Abstract :
The paper proposes a method to form 3D images with improved resolution and significantly decreased frame rates. The method is based on a linear phased array with a cylindrical lens that is moving in the direction perpendicular to the electronic scanning plane. The theory, the algorithms of the dynamic focusing in 3D space, the results of simulation and physical experiment results are given.
