摘要:

介绍了一种用于从高带宽天线阵列中获取高速瞬态数据的仪器样机。数公里的电缆使从广泛的天线阵列获取如此大带宽的无线电信号变得复杂。使用模拟光纤链路的解决方案正在探索中,尽管非常昂贵。我们提出了一种廉价的解决方案,允许每个天线元件的单独操作,操作在潜在的高本地自触发率。数字化数据包通过市场上可买到的千兆位以太网硬件传输到地面。然后,通过使用标准网络设备对接收到的数据包进行排序,在计算机群上重建事件,从而消除了对自定义、非常高速的触发硬件的需要。这样的系统是完全可扩展的,并且利用了电信行业的巨额资本投资。从示范样机的测试结果。

英文摘要:

An instrumentation prototype for acquiring high-speed transient data from an array of high bandwidth antennas is presented. Multi-kilometer cable runs complicate acquisition of such large bandwidth radio signals from an extensive antenna array. Solutions using analog fiber optic links are being explored, though are very expensive. We propose an inexpensive solution that allows for individual operation of each antenna element, operating at potentially high local self-trigger rates. Digitized data packets are transmitted to the surface via commercially available Giga-bit Ethernet hardware. Events are then reconstructed on a computer farm by sorting the received packets using standard networking gear, eliminating the need for custom, very high-speed trigger hardware. Such a system is completely scalable and leverages the hugh capital investment made by the telecommunications industry. Test results from a demonstration prototype are presented.
