Abstract: In the process of exhaustive synthesis of thinned arrays(whose elements are thinned from the uniform grid), enumerating the configuration of linear thinned arrays is main task of design. Followed by the analyses of element spacing synthesis, two enumerate algorithms of exhaustive study on configuration of linear thinned arrays are proposed in this paper, they are recursion algorithm and binary sequence enumerate algorithm. Some comparison studies on their performance are made in order to reveal the doable relations with the thinned ratio and aperture of the arrays. The results of computer simulation show the efficiency and applicability of the algorithms respectively. Finally, their performance trials reveal the applicability when they are applied to element spacing synthesis.
