| 摘 要： | 目前许多高分辨算法只适用于均匀线列阵的方位估计.在不规则阵列条件下,需将实际阵列等效为虚拟均匀线列阵.文中通过对基于扇区内插法设计虚拟均匀线列阵的研究,给出了设计的具体步骤,并提出一个简单且准确的虚拟线列阵阵元间隔的计算公式.

| Abstract: | Many attractive high resolution algorithms can be applied to estimate the direction-of-arrival(DOA) only when the array is linear and uniformly-sampled, so it is necessary to transform the real array into a synthetic linear and uniformly-sampled array, and the problem can be solved by using sector interpolation algorithm. The design process of such synthetic array is given and a simple and correct formula of calculating the interval between sensors of the synthetic linear and uniformly-sampled array is put forward. |
