波束形成是声纳信号处理系统中的核心部分——通过空间滤波取得空间增益的处理方法。数字多波束形成的算法具有Ｉ／Ｏ数据率高、计算量大的特点，在普通处理器上难以实现。文中介绍了一种采用高性能ＤＳＰ处理器ＳＨＡＲＣ实现实时数字多波束形成的处理方案，着重于其中的并行处理。
Beamforming is the core part of sonar signal processing system - the method to get the space gain through spatial filtering. The algorithm of digital multi-beamforming has the characteristics of high data rate of I / O and large amount of calculation, which is hard to be realized in ordinary processor. This paper introduces a high-performance DSP processor SHARC real-time digital multi-beam forming processing solutions, focusing on one of the parallel processing.
