Application of Constant Width Beamfoming Simulator SWARRAY to Underwater Communication System

将波束形成技术用于远程水声通信系统,可以提高接收信噪比。为了具体分析波束形成技术在水声通信中的应用,给出了用于任意阵形的宽带恒定束宽波束形成软件—SWARRAY。基于改进的自适应波束综合方法及时域宽带波束形成技术,软件可以合成各种运动状态下基阵的输出信号,为评估现实信道条件下波束形成技术在水声通信系统中的应用性能提供基础。结合直接序列扩频方案,验证了设计软件在水声通信仿真中的有效性。

The SNR of the received signal can be increased in long range underwater communication with beamforming technology. A constant width beamforming simulator SWARRY was proposed in order to evaluate the performance of beamforming technology to underwater communication systems, Based on improved adaptive beam synthesis method and time domain beamforming technology, the simulator could simulate array output at different conditions. Combined with a direct sequence spread spectrum system, its validity in underwater communication simulation was proved.
