摘  要:
High -speed data acquisition is a key part of the radar acquisition system.Basing on PCI bus technology,the data collection method is presented.The paper mainly introduces the hardware are design which takes Xilinx's CPLD controling module chip XC95144XL and bus interface chip PLX9054 as the core of the multichannel data acquisition card,including principle design,chip seletion and PCB design,eta.Through test and experiment in the ground-penetrating radar to detect underground mineral resources,it is shown that this method can meet the requirement of effectively transmitting and processing data in real time.
