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。-To reach the special requirements interferometric synthetic aperture sonar system signal source based on the the SOPC technology of FPGA implementations, the signal source is provided to the transmitter and analog signal back to the echo signal acquisition system clock and synchronization signal in order to ensure the consistency of the signal system time, but still give the time-varying gain signal receiver of the echo signal attenuation compensation the other hand, real-time acquisition and transmission of the sonar system in underwater sports attitude, depth, pressure, etc. Information After the lake trial and sea trial, the source system to complete the testing of analog and digital signals indicators meet the design requirements.
