摘要:

我们为阿塔卡玛大型毫米/亚毫米阵研制了FX结构的数字光谱相关器--阿塔卡玛紧凑阵关联函数。ACA关联函数处理来自多达16个天线的带宽为2 GHz的4对双极化信号,并计算包括16个天线的所有组合中的交叉极化的自相关谱和互相关谱。我们报告了关联函数的详细设计和关联函数硬件的验证结果。

英文摘要:

We have developed a FX-architecture digital spectro-correlator, Atacama Compact Array Correlator for the Atacama Large Millimeter/submillimeter Array. The ACA Correlator processes four pairs of dual polarization signals, whose bandwidth is 2 GHz, from up to sixteen antennas, and calculates auto- and cross-correlation spectra including cross-polarization in all combinations of sixteen antennas. We report the detailed design of the correlator and the verification results of the correlator hardware.
