The synthesis of frequency diverse arrays (FDAs) able to achieve time-invariant spatial focusing performance in the short-range is addressed. Two time-modulated optimized frequency offset schemes are presented that allow focusing the energy at a single target location and multiple target locations, respectively. A set of numerical examples is reported and discussed to validate the effectiveness of the proposed solutions also in comparison with the already proposed FDA design approaches.

Abstract
The synthesis of frequency diverse arrays (FDAs) able to achieve time-invariant spatial focusing performance in the short-range is addressed. Two time-modulated optimized frequency offset schemes are presented that allow focusing the energy at a single target location and multiple target locations, respectively. A set of numerical examples is reported and discussed to validate the effectiveness of the proposed solutions also in comparison with the already proposed FDA design approaches.| File | Dimensione | Formato | |
