This letter put forward a method of numerical optimization for the circular-aperture time- modulated grid array. The amplitude weight and the time modulation pulsewidth are …
The advantages of exploiting the harmonic patterns in a time‐modulated linear array (TMLA) is presented in this paper through mathematical validation and also applied for real‐world …
Unlike classical phased arrays, a key feature of time-modulated arrays (TMAs) is the ability to easily reconfigure the radiation pattern just modifying the pulse sequence that modulates …
