Abstract

Unlike conventional phased arrays that produce an angle-dependent radiation pattern, frequency diverse arrays (FDA) generate a radiation pattern dependent on the range, angle, and time, which results in the use of a frequency offset instead of the phase shift along the array. In recent years, a lot of research has been carried out on this topic, and various frequency arrangements, both linear and nonlinear, have been proposed which mainly use continuous waves to excite elements of array. In this paper, we use pulses instead of continuous waves, to stimulate the array elements, and we extend the array geometry to two dimensions, and we plot its radiation pattern for different times. The beam is formed and focused on a specific point by applying a coefficient weighting in the array.
