基于DSP的自适应数字波束形成的设计

Design of Adaptive Digital Beam forming System Based on DSP

提出了一种利用DSP实现基于阵列天线的数字波束形成的方案,对数字波束形成原理作了简单介绍。针对波束形成的数据量大,运算较复杂的特点,采用Freescale公司生产的MSC8144实现了数字波束形成的信号处理,实验结果表明,采用此种方法数字波束形成速度快、精度高。

The project of digital beam forming in antenna arrays was suggested based on DSP. A simple expatiation of the principle on digital beam forming was introduced. Against the characteristics of amount of data and complex operations in the procession of beam forming, the signal procession of digital beam forming was achieved by adopting MSC8144 produced by Freescale company. The result from tests expatiated that the speed of beam forming was rapid and the precision was high.
