Abstract
Code excitations have been applied to the newly developed two-way dynamic focusing imaging method using limited diffraction array beams. Image frame rate is increased several folds. Computer simulations with both point scatterers and objects consisting of random scatterers were performed to demonstrate the efficacy of the method.
