针对三维成像声纳在实际应用当中实时性的需求，在分析三维成像声纳波束形成算法原理和T M S320C6678多核任务并行处理的基础上，设计了基于T M S320C6678处理芯片的三维成像声纳二维波束形成算法的并行实现方法。该方法不仅能有效地完成二维波束形成，还能减少波束形成的计算量，满足系统的实时性需求。实验表明：该方法有效、可靠地完成了2304通道的二维波束形成，角度分辨率优于1°，满足实际系统实时性要求。

Aiming at the real-time requirement of the 3D acoustical imaging sonar in practical use ,this paper analyzes the beam-forming method of the 3D acoustical imaging sonar in multicore DSP ,and de-signs a 2D beam-forming method of the sonar based on TMS320C6678 .The method is not only used to form a 2D beam efficiently ,but also to decrease the computational complexity to meet the real-time requirement of the system .The experiment results show that the method is reliable and effective , enough to fulfill the 2D beam-forming with 2034 array elements and acquire the angle resolution supe-rior to 1° .T he performance test proves that the method can meet the real-time requirements of the ac-tual system .
