Abstract
A method and device for implementing an FPGA-based large-scale radio frequency interference array correlator are provided. The method includes: obtaining the number of channels of data of a radio frequency interference array, and performing average division; calculating the total correlation of data group and the total correlation between the data group and other data groups respectively through corresponding correlation calculation modules, and performing an accumulation calculation in an integration period to complete the total correlation operation of the radio frequency interference array. By means of grouping division and time division multiplexing, the FPGA resource is effectively utilized, and the calculation process of FPGA is simplified. The new method is suitable for the operation process of the system with high parallelism and high real-time requirements, and provides a high-efficiency solution for the real-time calculation of massive data of the large-scale radio frequency interference array.
