而对于平面任意阵列，提出了一种阵列内插的多扇区方位角估计方法。

For arbitrary planer array, we may adopt a kind of array interpolation method that can estimate azimuth of the signals in multisectors.

接着，介绍了基于内插的MPSK信号符号同步的算法，以及各模块的硬件实现。

And then, the algorithm based on the interpolation of MPSK symbol synchronization, as well as the hardware implementation of the modules is introduced.
