| 摘 要： | 子阵级的自适应处理可以用小代价获得比较好的处理性能，对于大型面阵的数据处理，提出了一种方法来划分非均匀子阵。计算机仿真结果表明，这种子阵结构的自适应方向图不但没有栅瓣，而且其主副瓣差值可以达到30dB以上，并可以在干扰方向和杂波处形成了很深的凹口。

| Abstract: | Good performance can be obtained by partially adaptive processing at subarray level where the key task is reduced to how to optimize the subarray partition.For the processing of data received from large planar arrays,a method is proposed of grouping subarrays,with its simulation results compared with that of the equal noise power method.Simulation results show that subarray configuration optimized by the method proposed does not have any obvious grating lobes and its adaptive antenna pattern and adaptive pe... |
