火控雷达的阵面设计技术

摘要

在火控雷达的阵面设计中子阵划分是提高雷达性能的有效手段。对阵面进行建模，得出了使用非规则子阵对天线阵面的精确划分方法。通过仿真给出了典型的阵面划分实例，并分析了阵列在宽带条件下的方向图性能，证明了所设计的阵面在抑制栅瓣方面具有优良的性质，能够提高火控雷达的性能。%In fire control radars,the subarray partitioning is usually employed to improve the performance of radars. This paper sets models of array to obtain the exact partition of array antenna with irregular shaped subarrays. Numerical examples of the subarray partition are given to validate the effectiveness 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.
