多波束形成方法及其实现

声纳往往采用相控偏转的技术来形成各个方向的发射/接收波束。相控阵可以利用简单的数字电路来实现基阵发射角度的偏转。文中介绍一种利用FPGA芯片来实现旋转单波束方式的发射波束。该方法设计简单、可靠,经过实验测试,整机达到了预期的效果,验证了发射波束形成方法的正确性。

Multi-beam forming technique and application

In sonar,phased deflexion is often used to form transmitting/receiving beams in diff-erent directions.Deflexion of transmitting array beams is realized with a simple digital circuit in the phased array.This paper introduces implementation of transmitting beams that rotates single beams based on FPGA.The design is simple and reliable.Experimental results show that the method of the transmitting beamforming is correct.
