摘    要:
为达到干涉合成孔径声纳系统对信号源的特殊要求,提出了一种基于SOPC技术的FPGA实现方法,该信号源一方面提供给发射机模拟信号,还给回波信号采集系统提供时钟和同步信号以保证信号系统时间一致性,同时还给接收机的时变增益信号实现对回波信号衰减的补偿;另一方面还实时采集并传输声纳系统在水下的运动姿态、深度、压力等信息;经过湖试和海试,该信号源系统完成了模拟信号和数字信号各项指标的测试,满足设计要求。

关 键 词:干涉合成孔径声纳  SOPC  FPGA

Abstract:
In order to achieve Interference synthetic aperture sonar system to the special requirements of the signal source,this paper presents a FPGA-based SOPC technology implementations,the signal provided to the transmitter analog signal on the one hand,returned to the echo signal acquisition system clock and sync signal in order to ensure consistency of the signal system time,as well as to the receiver signal to achieve time-varying gain compensation for attenuation of the echo signal;the other hand,also real-time collection and transmission system in the underwater sonar motion attitude,depth,pressure and other information;through lake test and sea trials,the signal source system to complete the analog signal and digital signal indicators test,satisfy the design requirements.
Keywords:Interference synthetic aperture sonar  SOPC  FPGA
