Abstract

The invention relates to a multi-connected domino sparse antenna and an array arrangement method thereof. The formation method includes: adopting an intelligent simulation algorithm, using L-shaped and Z-shaped tetragonals, can realize full coverage of any size of the formation, and will not leave blank spaces that cannot be covered. The embodiments of the present invention can have sufficient randomness to ensure that the array antenna does not appear grating lobes in a large scanning range.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of radio communication, and in particular to a multi-domino sparse antenna and an array arrangement method thereof. Background technique [0002] Due to its low cost and superior performance, sparse phased array antennas are widely used in the field of radar. R.J.Mailloux proposed a method of using L-shaped or other forms of multiple domino-type units to form a sparsely distributed phased array antenna. This form of sparsely distributed array has a high aperture utilization rate, and the array distribution has sufficient randomness. Grating lobes can be greatly reduced. [0003] In related technologies, there are various algorithms for realizing this array arrangement. Among them, the genetic algorithm is used to calculate the domino array of the antenna front, and the genetic algorithm refers to the method of searching for the optimal solution by simulating the natural evolution ...
