Abstract

The invention discloses an optimal design method for a multi-connected domino irregular sub-array plane. The optimal design method comprises the following steps: 1, determining a dictionary matrix through array plane aperture distribution and multi-connected domino sub-array types; 2, acquiring a sampling matrix of the optimal scanning directional diagram; 3, selecting an initial point based on amulti-task Bayesian compressed sensing algorithm; 4, solving and optimizing the dictionary matrix by using an iterative convex relaxation algorithm; and 5, checking whether an iteration result meets an accurate coverage condition or not, and outputting a final solution or backtracking the step 4. According to the optimal design method, a convex relaxation iteration-based set coverage model solvingmethod is creatively provided, so that the 0 / 1 integer programming problem in the sub-array layout can be effectively solved; sub-array layout schemes meeting the accurate paving condition can be effectively and optimally selected, and the output design result can meet the requirements for aperture efficiency maximization and relatively excellent scanning electrical performance at the same time;and different modular multi-connected domino sub-array design schemes can be customized according to different requirements.

Description

[0001] 【Technical field】 [0002] The invention relates to an optimal design method for an irregular sub-array of multiple dominoes, which belongs to the field of phased array antenna design in radar and communication systems, and specifically relates to an array layout design method based on an irregular sub-array of modular dominoes . The invention can be used in fields such as an active phased array radar system, a next-generation 5G communication phased array antenna system, and the like. [0003] 【Background technique】 [0004] At present, phased array / digital array radar plays an important role in military applications such as strategic early warning, space surveillance, air defense and anti-missile. With the increasingly complex electromagnetic environment on the battlefield, the military puts forward higher requirements for its combat technical indicators, resulting in an increasingly larger array aperture, and the number of array elements can easily reach tens of thou...
