摘　　要：多通道同步采集系统是阵列信号处理系统中的重要环节。分别采用THS1207与AD7864和FPGA两种不同的ADC采样模块,与ADSP-TS101的多处理器结构连接,实现了两种多通道同步采集和数据实时传输系统。实验结果表明,两种数据采集系统都具有良好的数据相位一致性,并且通道选择灵活,系统控制简单。系统具有良好的通用性和稳定性,实现了阵列信号处理算法的实时处理。Multi-channel synchronal sampling system plays an important role in array signal processing system. ADC sampling modules of THS1207 and AD7864 with FPGA are adopted to respectively connect with multi-processor system based on ADSP-TS101. The two systems with multi-channel synchronal sampling and data real-time transmission are realized. The experiment results show that they both have some advantages of phase consistency to sampling data, channel-chosen flexibleness and system-control easiness. And the systems have good universality and stability. As a result, the algorithms about array signal processing are implemented in real time.
