摘要：

Cross correlator is the core device of the cross-correlation flow measurement system. This paper describes the theory of the cross-correlation flow measurement system and realizes the digital correlator for flow measurement based on field programmable gate arrays (FPGA). The correlation algorithm is realized by verilog language, and the result of Modelsim simulation shows that this correlator can be used to calculate the cross functions of random signal. This correlator which has a simple hardware structure, high reliability and high accuracy, can meet the demand of the real-time flow measurement system.
