The synthesis of time-modulated linear arrays (TMLAs) is addressed in this work by considering the optimization of the switch-on instants of the radio-frequency (RF) switches used to modulate the static element excitations. It is shown that these additional degrees of freedom can be exploited to maintain some features of the radiation pattern more constant throughout the modulation period. Representative...
An innovative and computationally effective approach to the synthesis of optimal sum and difference patterns via uniformly spaced arrays with a number of common excitations is presented and assessed. The proposed technique takes advantage from known results in the (separate) optimal synthesis of sum and difference patterns and allows one to manage arbitrary and different bounds concerning both the...
This contribution presents an innovative approach based on an optimal excitation matching procedure. By exploiting the relationship between independently-optimal sum and difference patterns, the dimension of the solution space is considerably reduced and efficiently sampled by taking into account the presence of array elements more suitable to change sub-array membership. In the following, the proposed...
