Abstract :
In this study, a methodological beam steering approach in time-modulated linear arrays with simultaneous beam sidelobe control is presented. The method is based on the difference between pulse amplitude in order to provide necessary phase shift to steer the main beam and control the sidelobe level in harmonic frequencies. In order to illustrate the asserted idea a 16 element linear array placed alog z-axis with zero phase is considered. The results show that the proposed approach is an effective method in both beam steering and sidelobe level control.
