摘　　要：介绍了一种利用多DSP实现基于直线阵列的数字多波束形成方案,通过对直线阵列的特征和数字多波束形成原理的阐述,并结合TI公司TMS320F206硬件的特点利用单波束准实时叠加的方法实现了数字多波束形成的信号处理目的,实验结果表明,采用此种方法多波束形成速度快,扩展性能好.A method of digital muhi-beamforming in linear arrays was introduced based on multiple DSPs. By the expatiation of the characteristics of linear arrays and principle of digital multi-beamforming, the real-time signal processing of multi-beamforming was achieved, which used the method of single beam Guasi-realtime superposition. TI＇ s DSP-TMS320F206 are used to be the processors in the system. The result indicates that the speed of beamforming is rapid and expansibility is good.
