摘要
对大型阵列进行子阵划分能减少系统控制的路数,子阵级加入时延控制扩展了瞬时带宽。对子阵划分进行重叠排布,提供了窗函数的效果,有效抑制了由子阵划分所引起的过密栅瓣。子阵单元级和子阵级分别进行加权操作,提供了较低的副瓣。
Dividing large-scale array into subarrays can reduce the system control routes. In oroer to widen instantaneous bandwidth,the time delay control is introduced in subarray. Window function effect can be provided by overlapping subarray division, which effectively suppresses the over crowded grating lobe due to subarray division. Weight is separately performed in subarray unit level and subarray level,which provides relatively low side lobe.
