Array Design Technology for Fire-control Radars

In fire control radars,the subarray partitioning is usually employed to improve theperformance of radars. This paper sets models of array to obtain the exact partition of array antennawith irregular shaped subarrays. Numerical examples of the subarray partition are given to validate theeffectiveness of subarrays,and the array pattern performance is analyzed under the wideband condition,which indicates the advantage of the designed subarray architecture to improve performance of radars.
